Operating Instructions

aiR shutteR (VentuRi):

The air shutter plays a very important role in flame appearence and combustion quality. The shutter adjusts how much air gets mixed with the gas before it ignites. Adjustments can be made to accomodate various climates and vent configurations.
To gain access to the air shutter remove the safety screen and intake shield. There is a lever underneath the firebox near the gas valve as shown in Figure 3. Moving the lever to the right will close off the air mixing with the gas and will make the flame appear more yellow and tall. Moving the lever to the left will open up the shutter allowing more air to be mixed with the incoming gas; this will make the flames appear more blue and short.

Figure 3: Air shutter adjustment lever
noRmaL sounDs DuRing opeRation:

Typically natural gas flames will require the shutter to be more closed.
Typically LP flames will require the shutter to be more open.
If you cannot attain the proper flame by making air shutter adjustments then you may have the incorrect exhaust restrictor.
If the flame is very flickery, fast moving, and low then increase the restriction.
If the flame is very tall, lazy, and dirty then decrease the restriction.
More details can be found in the venting section of this manual.
Caution: Wear heat resistent gloves when making adjustments to the air shutter. Perform adjustments after 15 m inut es

Maintenance And Service
Routine maintenance:
At least once a year, run through the following procedures to ensure the system is clean and working properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not blocked by anything. The pilot flame should be blue with little or no yellow on the tips. Warning: Clearances must be sufficient to allow access for maintenance and service. Warning: Failure to position the parts in accordance with this manual, or failure to use only parts specifically approved with this appliance may result in property damage or personal injury. The venting system must be periodically examined; it is recommended the examination is done by a qualified agency.
cLeaning the gLass:
When the fireplace has cooled, remove the safety screen and glass door. See maIntenance anD serVIce – glass Door remoVal. Check the gasket material on the back of the glass, making sure that it is attached and intact. During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all fireplaces. However, this condensation can allow dust and lint to cling to the glass surface. I nitial paint curing of the appliance can leave a slight film behind the glass, a temporary problem. The glass will need cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth. Abrasive cleaners will damage the glass and painted surfaces. Depending on the amount of use, the glass should require cleaning no more than two or three times a season. Do not clean the glass when it is hot
cLeaning the FiRebox:
Remove the logs carefully, as they are very fragile. Gently remove all the media and place on a paper towel. Vacuum the bottom of the firebox thoroughly. Carefully clean any dust off the logs and remove any lint from the burner and pilot. At this time, inspect the burner tube for cracking or severe warping. I f a problem is suspected, contact the dealer. Check the logs for deterioration or large amounts of soot; a small amount on the bottom side of the logs is normal. Replace the logs as shown in the seconDary InstallatIon – log set InstallatIon section. I f new/ more media is required, contact your nearest ENVI RO dealer.
RepLacing the gLass:
The glass in the fireplace is a high temperature ceramic. If the glass is damaged in any way, a factory replacement is required (see Parts lIst). Wear gloves when handling damaged glass door assembly to prevent personal injury. Do not operate with the glass front removed, cracked or broken. Removal and replacement of the glass from the door must be done by a licensed or qualified service person. The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed. To remove the door (see page 17). The replacement glass will come with a new gasket installed. Remove any silicone remnants from the door. Apply high temperature silicone to the two vertical faces of the door and install the new piece of glass with gasket (be sure to maintain edge clearances). Apply even pressure to the glass to allow the silicone to adhere to the gasket material.
15

Maintenance And Service
cLeaning DecoRatiVe suRFaces:
Painted and porcelain faces should be wiped with a damp cloth periodically. I f a plated face has been purchased, it should be unpacked/ unwrapped carefully to avoid getting anything on the surface of the finish, including cleaners, polish and finger prints. It is important to note that fingerprints and other marks can leave a permanent stain on plated finishes. To avoid this, give the face a quick wipe with denatured alcohol on a soft cloth BEFORE lighting the fireplace. Never clean the face when it is hot. Do not use other cleaners as they may leave a residue, which can become permanently etched into the surface.
saFety scReen:
A safety screen is installed from the manufacture to protect its users from the dangers of the hot glass preceding it. There are four safety screen mounting brackets that hold the screen into position as shown in Figure 17. I n order to remove the safety screen it is easiest to grab with both hands from the bottom and lift the screen up off the mounting brackets and outward.

Initial Installation
QUALIFIED INSTALLERS ONLY

All Enviro C-Series fireplaces may be installed in a covered outdoor area when following the requirements stated below:
· Fireplace must be installed in a weather proof enclosure while still following all clearance to combustible materials as outlined in the fireplace’s manual.
· The fireplace cannot serve as part of the building’s insulation or weatherproofing barrier. The building must be properly insulated and sealed from the outside prior to installation of the fireplace.

½A A
Figure 42: Overhang Depth Requirements

· The fireplace must be protected by an overhang with a depth that is at least equal to half of its height from the base of the fireplace, as shown in Figure 42.
Example – If the overhang height = 8ft (2.4m) then the required overhang depth must be at least 4ft ( 12m)
· The width of the covered overhang on each side of the fireplace must also be at least equal to half of its height
Example – If the overhang height = 8ft (2.4m) then the overhang must extend at least 4ft (1.2m) past each side of the fireplace opening
· Fireplace may only utilize the Cool Surface System (CSS), or any variant of it, when the covered overhang is flat with no pitch in front or to the side of the fireplace.
· For models equipped with remote control, neither “Smart Mode” nor Thermostat is permitted for use as this could lead to unintended continuous operation of the fireplace.
· Plated finish surround panels are not permitted for outdoor installation due to the high potential for oxidation to form on the surface.

· Any outdoor furnishings must be kept a minimum of 3ft (0.9m) away from the front of the fireplace. · Electrical and gas connections must follow applicable codes and standards pertaining to outdoor
inst allat ions.
· Horizontal termination caps must not discharge into the same space shared by the front of the fireplace. Vertical termination caps are recommended.

FLex Venting:

QUALIFIED INSTALLERS ONLY

This fireplace is certified to work with aluminium co-axial flex venting. Flex venting can be used in the same configurations as rigid pipe, see venting diagram for details. Flex venting is only to be used for the run, it must be adapted to rigid piping for exterior wall penetration and termination. Note: Adhere to all
rigid venting safety measures and clearances.

Use 5X8 Flex Adapter Kit [ 50-3789] : This kit will allow you to adapt co- axial flex to the fireplace, make your vent run, then adapt back to rigid venting (flex not included) .

Any Enviro Ap p ro ve d Rig id Ve nting

Any 5X8 CSA or UL flue gas certified aluminum or stainless steel flex is acceptable. Proper spacers must be used to keep pipes from contacting each other. Proper venting spacers must be used, nothing makeshift. Examples of allowable flex pipe brands include, but are not limited to, the following:
· M&G Duravent
· Selkirk Corp
· ICC
· Z-Flex
· Flexmaster
· Chim Flex
· Olympia

Figure 43: Flex Adapter Kit Install

I NSTALLATI ON NOTES: · Do not bend flex vent over 90 degrees. · All horizontal runs should have a minimum 1/ 4″ (6mm) rise per foot for optimal performance. · Do not allow the inner flex pipe to contact the outer pipe, keep it pulled tight and use spacer
springs. · Spacers are required at the start, middle, and end of each elbow to ensure gap is maintained. · Do not add any extensions to the preset kits, if more length is required, use rigid pipe. · No need for liquid sealant; secure flex venting with aluminum vent tape and apply sufficient
self-tapping screws.

cLeaRances & non-combustibLe :
When installing the C72I /C72ID as a zero clearance fireplace the correct clearances and materials must be used:
aboVe unit: A minimum 19″ ( 483mm) of non-combustible facing material must be used above the firebox opening. in FRont oF unit: The C72I can be placed on a combustible floor if desired. The unit cannot sit directly on combustible flooring other than wood. aDjacent/siDewaLL: A minimum of 5 3/ 16″ ( 132mm) of non-combustible facing materials must be used of the side of the firebox opening above the bottom edge openeing. There must be a minimum distance of 7″ ( 229mm) from the finishing edge of the C72I / C72ID to an adjacent wall composed of combustible material.
mantLe: I t is not necessary to install a mantle, but if one is desired the guidelines as shown in Figure 34 & Figure 35. The minimum clearance from the side of a mantle to wall is 4″.
FLooR: There must be a minimum distance of 10″ ( 254mm) from the bottom finishing edge of the C72I / C72ID to a floor composed of combustible material, unless the Cool Surface System is installed. If the CSS is installed, There must be a minimum distance of 1″ ( 25mm) from the bottom finishing edge of the C72I / C72ID to a floor composed of combustible material
cRacking: The most common area of cracking is along the horizontal cement board/ drywall transition; placing this transition further away from the heat will help prevent cracks. If you have concerns of excessive finishing wall temperature follow one of these options to minimize the possibility of cracking:
1. I nstall the optional heat distribution kit (50-3455 or 50-3713). 2. Install concrete board higher than the minimum specified dimension. 3. Add a decorative tile trim over the drywall transition area.

QUALIFIED INSTALLERS ONLY tV instaLLation consiDeRations:
If you are planning to mount a TV above your fireplace some considerations must be made to ensure it is protected from the heat. A recess, mantel, or a combination of both will be needed in order to keep the heat away from the TV. To insure protection of electronics and art above the fireplace the Cool Surface System option is available (50-3455 or 50-3713), this reduces wall temperatures greatly while still providing heating.
During testing temperatures did not exceed 150°F (65°C) in a 5″ deep recess. There is no guarantee that these temperatures will not harm the longevity of your TV. Make sure to consult your TV manufacture’s specifications to find the maximum allowable operating temperature. Since every home and installation is unique, temperatures should be verified at the time of install if possible. A TV should not be installed if temperatures exceed the manufacturers maximum allowable temperature.
See Figure 45 and Figure 46 for minimum TV installation clearances. Make sure there is 2″ of clearance around the sides and top of the TV to allow for airflow. Remember these are minimum dimensions increasing them can only help reduce the temperature the TV is subjected too.
I f installing with a mantel to protect the TV please see Figure 45 for clearances, it is highly recommended to use at least a 8″ mantel. The minimum distance from the base of the unit to the bottom of the TV would be 45.75″.
I f a recessed installation is desired please see Figure 46 for TV clearances. The recess will need to protrude from the wall for proper protection, this dimension is dependant on the TV and TV mounting bracket depth. The minimum distance from the base of the unit to the bottom of the TV would be 47.00″.

Exhaust Pipe Combustion Air Outer Pipe

5. For buildings with vinyl siding, a vinyl standoff should be installed between the vent cap and the exterior wall. Attach the vinyl siding standoff to the

Figure 52: Horizontal Vent Termination

horizontal termination. Note that the termination bolts onto the flat portion of the standoff, providing an air space between the wall and the vent termination. The air gap prevents excessive heat from possibly melting the vinyl siding.

6. Horizontal pipes must be supported every 3′ ( 914 mm) . Plumber’s all round strap will suffice. 7. Ensure venting clearances are maintained, see page 36 for details.

Step 1. Set the fireplace in the desired location. Check to determine if wall studs will be in the way when the venting system is attached. If this is the case, the location of the fireplace may have to be adjusted or the venting may have to be offset.

Step 2. Direct vent pipe sections are designed with special twist-lock connections. Dry fit the desired combination of pipe and elbows to the appliance adaptor.

Step 3. With the pipe in the correct position and attached to the fireplace, mark the wall for a hole as directed by specified wall thimble dimensions. Cut and frame the hole in the exterior wall where the vent will be terminated. I f the wall being penetrated is made of a non-combustible material
(i.e. masonry or concrete) a 8 1/ 2″ ( 216 cm) hole is acceptable.

Step 4. With the hole now framed, the wall thimble installed, and the pipe extending into the wall, proceed to the outside. Attach the termination to the pipe using RTV and Mil-Pac or Rutland No 78 Stove and Gasket Cement to seal joints. The vent pipe must extend into the vent cap at least 1¼ inches ( 32 cm) . Secure the connection between the vent cap and the pipe by attaching the two (2) sheet metal straps, which extend from the vent cap assembly to the outer wall of the vent pipe. Bend any remaining portion of the strap back towards the vent cap. Security Secure Vent uses a twist lock cap.
Step 5. Position the horizontal vent termination in the center of the 10″ ( 254 cm) square hole and attach to the exterior wall with the four screws provided. The arrow on the vent termination should be pointing up. Run a bead of non-hardening mastic around the edges of the vent cap, to make a seal with the wall. Ensure the proper clearances to combustibles have been m aint ained.

VeRticaL teRmination:
Step 1. Check the instructions for required clearances (air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces. Do not pack air spaces with insulation.
Step 2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to the position of the appliance flue exit, and mark the location where the vent will penetrate the ceiling. Drill a small hole at this point. Next, drop a plumb bob from the roof to the hole previously drilled in the ceiling, mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters, or other framing will obstruct the venting system. You may wish to relocate the appliance, or to offset, to avoid cutting load bearing members.
Step 3. To install the Round Support Box/Wall Thimble in a flat ceiling, cut a 10 ” ( 254 cm) square hole in the ceiling, centered in the hole drilled in Step 2. Frame the hole as shown in Figure 53.

Step 4. Assemble the desired lengths of black pipe and elbows necessary to reach from the appliance adapter up through the Round Support Box. I nsure that all pipe and elbow connections are in their fully twist-locked posit ion.

Step 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should be of sufficient size to meet minimum requirements for Clearance to Combustibles, as specified. Continue to assemble lengths of pipe and elbows necessary to reach from the ceiling support box up through the roof line. Galvanized pipe and elbows may be utilized in the attic, as well
as above the roof line. The galvanized finish is desirable above the roof line, due to the higher corrosion resistance.

Step 6.

Once the pipe sections have been joined, and run up through the hole in the roof, slip an elbow strap over the exposed sections, bend the support straps outwards, and push the elbow strap down to the roof level, as shown in Figure 53. Tighten the clamp around the pipe section. Use
a level to make sure the pipe is truly vertical. With roofing nails, secure the support straps to the roof. Seal the nails holes heads with non-hardening mastic. Trim the excess length of the
support straps that extend out beyond the edge of the flashing.

Step 7.

Slip the flashing over the pipe section protruding through the roof. Secure the base of the flashing to the roof with roofing nails. Use a non-hardening sealant between the uphill edge of the flashing and the roof. Insure the roofing material overlaps the top edge of the flashing. Verify that you have at least the minimum clearance to combustibles at the roof line.

Step 8.

Continue to add pipe sections until the height of the vent cap meets the minimum code requirements. Refer to Figure 54 and Table 7. Note that for steep roof pitches, the vent height must be increased. I n high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors can result in poor draft, or down drafting. I n these cases, increasing the vent height may solve the problem.

Step 9. Slip the storm collar over the pipe, and push it down to the top of the roof flashing as shown in Figure 53. Use the non-hardening sealant around the joint between the pipe and the storm collar.

Step 10. Twist-lock the vent cap.

NOTES:
( 1) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3′ ( 914 mm) , to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (see Figure 55).
( 2) When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow offers less restriction to the flow of flue gases and intake air.
( 3) For multi story installations; a ceiling firestop is required at the second floor, and any subsequent floors (see Figure 56). The opening should be framed to 10″ ( 254 mm) x 10″ ( 254 mm) inside dimensions, in the same manner as shown in Figure 48.

Figure 55: Use of Wall Straps.
( 4) Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent passes through, must be enclosed. The enclosure may be framed and sheet-rocked with standard building materials. However consult the appliance manufactures installation instructions for the minimum allowable clearance between the outside of the vent pipe, and the combustible surfaces of
the enclosure. Do not fill any required air spaces with insulation.
