  Figure 3.5 Clearances to Combustibles
  D. Constructing the Appliance Chase
  NOTICE: Install appliance on hard metal or wood surfaces extending full width and depth. DO NOT install directly on carpeting, vinyl, or any combustible material other than wood.
  WARNING!** Risk of Fire! Maintain specified air space clearances to appliance and vent pipe:

  • Insulation and other materials must be secured to prevent accidental contact.
  • The chase must be properly blocked to prevent blown insulation or other combustibles from entering and making contact with fireplace or chimney.
  • Failure to maintain airspace may cause overheating and a fire.

A chase is a vertical box-like structure built to enclose the gas appliance and/or its vent system. In cooler climates the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield firestops and construction of the chase may vary with the type of building. These instructions are not substitutes  for the requirements of local building codes. Therefore,you MUST check local building codes to determine the requirements to these steps.
NOTICE: Where required by code, install only sprinklerheads with a sprinkler activation temperature classifiedas Extra High.

• Sprinklers inside of chase: Keep sprinkler head away from vent and chimney.
• Heat Management applications: Maintain 36 inches of clearance to openings from which heat is discharged such as convection slots, heat zone registers, etc. Refer to Section 6.B for Heat Management options allowed for this appliance.

Chases should be constructed and insulated in the same manner as the thermal envelope of the home based on the code requirements for that climate zone to prevent air leakage and draft problems. The chase is an extension of the building thermal envelope.
To further prevent drafts and air leakage, the wall shield and ceiling firestops should be sealed with caulk with a minimum of 300 ºF continuous exposure rating to seal gaps. Gas line holes and other openings should be sealed with caulk with a minimum of 300 ºF continuous exposure rating or stuffed with unfaced insulation. If the appliance is being installed on a cement surface, a layer of plywood may be placed underneath to prevent conducting cold up into the room.
Minimum height requirements for an exterior chase on a topvented appliance are shown in Figure 3.6. Reference Figure 4.4 for additional clearances.
NOTE: If overhang (Dim. A) is less than 2 inches, clearance from top of termination cap to bottom of overhang (Dim. B) may be 0 inches. Dimension A is measured from the edge of the overhang to the surface the termination cap is mounted to.
Figure 3.6 Exterior Chase – Minimum Height Requirements
E. Floor Protection
Vinyl Flooring
Vinyl flooring is sensitive to heat. Hearth and Home Technologies does not recommend adhesive based vinyl flooring due to thermal expansion. Floating- style flooring can be used, but will reach temperatures up to 110 °F in a room with ambient temperature of 70 °F. Consult flooring specifications to ensure compatibility.

Figure 4.6 Vertical and Horizontal Offset for DVP and SLP Elbows
Note: Back to back 45 degree or 90 degree elbows have no additional vertical or horizontal value and are not included in determining maximum vent run lengths.
E. Vent Diagrams

General Rules:

• A maximum of three 90º elbows (or six 45º elbows) may be used in any vent configuration. Some elbows may be installed horizontally. See Figure 4.15.
• A maximum of four 90º elbows (or eight 45º elbows) may be used in a top vented, vertically terminated vent configuration. See Figure 4.22.
• Elbows may be placed back to back anywhere in the system.
• Any 90º elbow may be replaced with two back to back 45º elbows.
• When penetrating a combustible wall, a wall shield firestop must be installed.
• When penetrating a combustible ceiling, a ceiling firestop must be installed.
• Horizontal runs of vent do not require vertical rise;  horizontal runs may be level.
• When the horizontal termination cap is exposed to high precipitation, the cap should have a 1/4 inch downward slant to allow any moisture in cap to be released. See Figure 4.7. See Figure 4.8 for additional water infiltration prevention information.

Measuring Standards

Vertical and horizontal measurements listed in the vent diagrams were made using the following standards:

• Pipe measurements are shown using the effective length of pipe. See Section 12.A (Figure 12.1 for DVP, Figure 12.9 for SLP) for information on effective length of pipe components.
• Horizontal terminations are measured to the outside  mounting surface (flange of termination cap) (see Figure 4.9).
• Vertical terminations are measured to top of last section of pipe. See Figure 4.10.
• Horizontal pipe installed level with no rise.

Figure 4.11 Measure Horizontal and Vertical Termination Clearance to Trapezoid Portion of Cap
Note: The NDV series appliances can adapt to SLP series vent pipe when venting off the top of the appliance. You must use a DVP-SLP24 adapter or a DVP-2SL and two feet of SLP pipe which can only be attached to the appliance starting collar.
When looking at horizontal termination diagrams, neither adapter is counted as part of the minimum vertical (V1 min.) requirements.
All venting rules for the vent run must still be followed.

Vent Clearances and Framing

A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to vent. DO NOT pack insulation or other combustibles:

• Between ceiling firestops
• Between wall shield firestops
• Around vent system

Failure to keep insulation or other material away from vent pipe could cause overheating and fire.

Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).

• DVP heat shield – designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184 mm) thick.
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.
• SLP heat shield – designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to 194 mm thick).
• If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed.
  If wall thickness is greater than 7-5/8 in. a DVP-HSM-B will be required.

• When using SLP pipe, minimum clearances from the vent pipe to combustible materials at inside wall firestops are:
  Top: 2-1/2 in. (64 mm)
  Bottom: 1/2 in. (13 mm)
  Sides: 1 in. (25 mm)
  Figure 5.1 Horizontal Venting Clearances To Combustible Materials
  B. Wall Penetration Framing/Firestops
  Combustible Wall Penetration
  Whenever a combustible wall is penetrated, you must frame a hole for the wall shield firestop(s). The wall shield firestop maintains minimum clearances and prevents cold air infiltration.

  • The opening must be framed on all four sides using the same size framing materials as those used in the wall construction.
  • SLP pipe – A wall shield firestop must be placed on each side of an interior wall. A minimum 1-1/2 in. (38 mm) overlap of attached heat shields must be maintained.
  • DVP pipe – A wall shield firestop is required on one side only on interior walls. If your local inspector requires a wall shield firestop on both sides, then both wall shield firestops must have a heat shield (refer to Section 12.A.) attached to them.
  • See Section 7.F. for information for regarding the installation of a horizontal termination cap.

Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-combustible materials such as concrete, a hole with diameter one inch greater than the pipe is acceptable. Whenever a non-combustible wall is penetrated, the wall shield firestop is only required on one side and no heat shield is necessary.
If your local inspector requires the wall shield firestop on both sides, then both wall shield firestops must have a heat shield attached to them.

  Figure 5.2 Wall Penetration

C. Ceiling Firestop/Floor Penetration Framing
WARNING! Risk of Fire! DO NOT pack insulation around the vent. Maintain clearances tovent to prevent overheating.

A ceiling firestop MUST be used between floors and attics.

• DVP pipe only – Frame an opening 10 in. by 10 in. (254 mm by 254 mm) whenever the vent penetrates a ceiling/floor (see Figure 5.3).
• SLP pipe only – Frame opening 9 in. x 9 in. (229 mm x 229 mm) whenever the vent penetrates a ceiling/floor (see Figure 5.3).
• Frame the area with the same sized lumber as used in ceiling/floor joist.
• The ceiling firestop may be installed above or below the ceiling joists when installed with an attic insulation shield. It must be under joists between floors that are not insulated. Refer to Figure 5.4.
• Secure in place with nails or screws.

D. Install Attic Insulation Shield

WARNING! Fire Risk. The use of an attic shield is required to prevent loose materials or insulation from contacting the vent causing overheating and a fire.
The International Fuel Gas Code requires an attic shield constructed of 26 gauge minimum steel that extends at least 2 in. (51 mm) above insulation.

• Attic insulation shields must meet specified clearances to combustible materials and be secured in place.
• An attic insulation shield kit is available from Hearth & Home Technologies. Contact your dealer to order. Install attic insulation shield according to instructions included with kit.

Attach the first pipe section to the starting collar:

• Lanced pipe end of the starting collar.
• Inner pipe over inner collar.
• Push the pipe section until all lanced tabs snap in place.
• Lightly tug on pipe to confirm it has locked.

Requirement for Commercial, Multi-family (Multi-level exceeding two stories), or High-Rise Applications
WARNING! Risk of Fire or Explosion! DO NOT break silicone seals on slip sections. Use care when removing termination cap from slip pipe. If slip section seals are broken during removal of the termination cap, vent could leak.
All outer pipe joints must be sealed using one of the methods below, including the slip section that connects directly to the horizontal termination cap.

• Apply a bead of silicone sealant (300 ºF minimum continuous exposure rating) inside the female outer pipe joint prior to joining sections. See Figure 7.1 OR Apply a bead of silicone sealant (300 ºF minimum continuous exposure rating) to the outside of connecting joint after joining sections OR
  Apply aluminum foil tape (300 ºF minimum continuous exposure rating) to the outside of connecting joint after joining sections. On horizontal pipe runs, it is recommended that the tape seam is positioned on the bottom side of the vent pipe.

• Only outer pipes need to be sealed. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated.

Assemble Pipe Sections
Per Figure 7.2:

• Start the inner pipe on the lanced end of section A into the flared end of section B.
• Start the outer pipe of section A over the outer pipe of section B.
• Once both vents sections are started, push firmly until all lanced tabs lock into place.
• Lightly tug on the pipe to confirm the tabs have locked.

It is acceptable to use screws no longer than 1/2 in. (13 mm) to hold outer pipe sections together. If predrilling holes, DO NOT penetrate inner pipe.
For 90º and 45º elbows that are changing the vent direction  from horizontal to vertical, one screw minimum should beput in the outer flue at the horizontal elbow joint to prevent the elbow from rotating. Use screws no longer than 1/2 in. (13 mm). If predrilling screw holes, DO NOT penetrate inner pipe.

Assemble Vent Sections (SLP Only)

To attach the first vent component to the starting collars of the appliance:

• Attach a DVP-SLP24 adapter to the starting collar of the appliance.
• Lock the vent components into place by sliding the pipe section onto the collar.
• Align the seam of the pipe and seam of collar to allow engagement. Rotate the vent component to lock into place. Use this procedure for all vent components. See Figure 7.5.
• Slide the gasket over the first vent section and place it flush to the appliance. This will prevent cold air infiltration.  Caulk with a minimum of 300 ºF continuous exposure rating may be used to hold the part in place.
• Continue adding vent components, locking each succeeding component into place.
• Ensure that each succeeding vent component is securely fitted and locked into the preceding component.

Required Commercial, Multi-family (Multi-level exceeding two stories), or High-Rise Applications
All outer pipe joints must be sealed with 100% silicone (300 ºF minimum continuous exposure rating), including the slip section that connects directly to the horizontal termination cap.

• Apply a bead of silicone sealant (300 ºF minimum continuous exposure rating) inside the female outer pipe joint prior to joining sections. See Figure 7.1. OR
  Apply a bead of silicone sealant (300 ºF minimum continuous exposure rating) to the outside of connecting joint after joining sections OR Apply aluminum foil tape (300 ºF minimum continuous exposure rating) to the outside of connecting joint after joining sections. On horizontal pipe runs, it is recommended that the tape seam is positioned on the bottom side of the vent pipe.

• Only outer pipes need to be sealed. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated.

• Slide together to the desired length.

• Maintain a 1-1/2 in. (38 mm) overlap between the slip section and the pipe section.
• Secure the pipe and slip section with two screws no longer than 1/2 in. (13 mm), using the pilot holes in the slip section. See Figure 7.7.

• Continue adding pipe as necessary following instructions in “Assembling Pipe Sections.”
  NOTICE: If slip section is too long, the inner and outer flues of the slip section can be cut to the desired length.
  NOTICE: When installing a vent system with an HRC termination cap, all pipe system joints shall be sealed using a high temperature silicone sealant (300 ºF minimum continuous exposure rating).

• Apply a bead of silicone sealant (300 ºF minimum continuous exposure rating) inside the female outer pipe joint prior to joining sections.

• Only outer pipes are sealed, sealing the inner flue is not required.

• All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed.

C. Secure the Vent Sections

• Vertical runs originating off the top of the appliance, with  no offsets, must be supported every 8 ft. (2.44 m) afterthe maximum allowed 25 ft. (7.62 m) of unsupported rise.
• Vertical runs originating off the rear of the appliance, or after any elbow, must be supported every 8 ft. (2.44 m).
• Horizontal runs must be supported every 5 feet (1.52 m).
• Vent supports or plumbers strap (spaced 120º apart) may be used to support vent sections. See Figures 7.8 and 7.9.
• Wall shield firestops may be used to provide horizontal support to vent sections.
• SLP ceiling firestops have tabs that may be used to provide vertical support.

• Insert a bolt (provided) through the brackets and install nut. Do not completely tighten.

• Slide the assembled storm collar down the pipe section until it rests on the roof flashing (see Figure 7.13).
• Tighten nut and make sure the collar is tight against the pipe section.
• Seal around the top of the storm collar. See Figure 7.14.

Install Vertical Termination Cap

• Attach the vertical termination cap by sliding the inner collar of the cap into the inner flue of the pipe section while placing the outer collar of the cap over the outer flue of the pipe section.
• Secure the cap by driving three self-tapping screws (supplied) through the pilot holes in the outer collar of the cap into the outer flue of the pipe (see Figure 7.14).

F. Horizontal Termination Requirements
Heat Shield Requirements for Horizontal
Termination
WARNING! Risk of Fire! To prevent overheating and fire, heat shields must extend through the entire wall thickness.

• DO NOT remove the heat shields attached to the wall shield firestop and the horizontal termination cap (shown in Figure 7.15).
• Heat shields must overlap 1-1/2 in. (38 mm) minimum.

There are two sections of the heat shield. One section is factory-attached to the wall shield firestop. The other section is factory-attached to the cap. See Figure 7.15.
If the wall thickness does not allow the required 1-1/2 in. (38 mm) heat shield overlap when installed, an extended heat shield must be used.

•  If the wall thickness is less than 4 in./102 mm (DVP) or 4-3/8 in./ 111 mm (SLP), the heat shields on the cap and wall shield firestop must be trimmed. A minimum 1-1/2 in. (38 mm) overlap MUST be maintained.
•  Use an extended heat shield if the finished wall thickness is greater than 7-1/4 in. (184 mm).
• The extended heat shield may need to be cut to length maintaining sufficient length for a 1-1/2 in. (38 mm) overlap between heat shields.
• Attach the extended heat shield to either of the existing heat shields using the screws supplied with the extended heat shield. Refer to vent components diagrams in the back of this manual.
• Rest the small leg on the extended heat shield on top of the pipe section to properly space it from the pipe section.

Important Notice : Heat shields may not be field constructed.

Install Horizontal Termination Cap (DVP and SLP Pipe)
WARNING! Risk of Fire! The telescoping flue section of the termination cap MUST be used when connecting vent.

• 1-1/2 (38 mm) minimum overlap of flue telescoping section is required.
  Failure to maintain overlap could cause overheating and fire.

• Vent termination must not be recessed in the wall. Siding may be brought to the edge of the cap base.

• Flash and seal as appropriate for siding material at outside edges of cap.

• When installing a horizontal termination cap, follow the cap location guidelines as prescribed by current ANSI Z223.1 and CAN/CGA-B149 installation codes and refer to Section 4 of this manual.
