INSTALLING THE VENTING SYSTEM

These models of wall furnaces are designed for direct venting through a wall. Only venting components specifically approved for these furnaces may be used. The flow of combustion gases and ventilation air must not be obstructed. Minimum clearance between pipes and combustible materials is one (1) inch (25.4 mm). Vent terminal must be 18.0” away from an adjacent wall. Minimum clearance between vent cap and combustible material 1-3/4”.

IMPORTANT:
THE VENT-AIR INTAKE SYSTEM MUST BE PROPERLY INSTALLED TO ENSURE PROPER AND SAFE OPERATION. THE VENT-AIR INTAKE SYSTEM MUST ALSO BE PROPERLY RE-INSTALLED AND RESEALED TO ENSURE PROPER AND SAFE OPERATION.

WARNING:
FAILURE TO POSITION THE PARTS IN ACCORDANCE WITH THESE DIAGRAMS OR FAILURE TO USE ONLY PARTS SPECIFICALLY APPROVED WITH THIS APPLIANCE MAY   RESULT IN PROPERTY DAMAGE OR PERSONAL INJURY

IMPORTANT:
THE APPLIANCE’S VENTING SYSTEM SHOULD BE INSPECTED AT LEAST ONCE A YEAR AND IMMEDIATELY CLEANED IF NECESSARY.

CAUTION:
ALL JOINTS MUST BE AIR-TIGHT.

CAUTION:
THE VENT PIPE MUST HAVE A SLIGHT DOWNWARD SLOPE. 1/4” PER FOOT.

The venting system consists of:

Table 3 Lengths Of Pipes And Rod.

Vent Pipe (B| Vent-Air Intake Pipe (C)| Rod (D)
Wall Thickness + 3-3/8“ (86 mm)| Wall Thickness + 2-1/2“ (64 mm)| Wall Thickness + 5-7/8“ (149.5 mm)

Measure thickness of the wall as shown in figure 13.

1. If any of the following are long trim them according to thickness of the wall, (s ee table 3) :

   • (B) vent pipe
   • (C) vent-air intake pipe
   • (i) insulation
   • (D) rod

2. The hole at the outside of the wall must be a square of 11-1/4” (286 mm) X 11-1/4” (286 mm) (see figure 15).

3. From the outside of the wall, screw the rod (D) slightly onto support located inside the appliance flue outlet.

4. Wrap the vent-air intake pipe (C) with the provided insulation (i) (foil side out) and place the provided strip of tape (H) down the seam to secure it

5. Slide the smaller vent pipe (B) (from outside your house) through the hole in the wall and attach to the mounted heater inside your house. Be sure the vent pipe is snug and engaged to the heater. Then slide the larger Vent‐Air Intake Pipe, with the insulation wrapped and taped to the outside of the pipe, through the same hole and over the smaller Vent Pipe (B) and attach to the heater.
   NOTE: It is critical that the insulation wrap (i) be wrapped and secured with the tape on the outside of the larger Vent‐Air Intake Pipe (C). The insulation is NOT to be wrapped in between Vent Pipe (B) and Vent‐Air Intake Pipe (C) (see figure 14).
   
   

6. The outdoor mounting plate (F) and the silicon rubber ring (G) should be installed between the vent cap (A) and the exterior wall. Note: For additional security the outdoor mounting plate (F) can be attached to the outside of the wall using the appropriate hardware for mounting to the surface of the building. The outdoor mounting plate (F) must be positioned flush to the wall and sealed with a non-hardening mastic (silicone caulk). Position the outdoor mounting plate (F) so that the vent-air intake pipe (C) has a slight downward slope of 1/4” per foot of venting to the outside.
   ATTENTION:
   THE DOWNWARD SLOPE IS NECESSARY TO PREVENT THE ENTRY OF RAINWATER.

7. Before attaching the vent cap (A) to the exterior wall, run a bead of non-hardening mastic (silicone caulk) around its outside edge, so as to make a seal between it and the outdoor mounting plate (F) (see figure 16).

8. Slide the vent cap (A) into position and secure into place using the provided nut (E). Tighten nut (E) down until the vent cap (A) leans against the outdoor mounting plate (F) (see figures 15 and 16).
   
   

INSTALLING THE THERMOSTAT SENSOR

In order to protect the thermostat sensor from any damage during shipping, or while handling it before it is definitely installed, the thermostat sensor has not been attached to its final location in the appliance. So, once the heater is installed, the thermostat sensor must be placed and secured in position. To do so, follow these steps

1. Reach in through the bottom of the unit and  cut the cable tie holding the thermostat sensor to the unit.
2. Place the thermostat sensor under the right bottom of the bracket and attach it with the provided medium screw (i) that fixes the appliance to the bracket as shown in figures 17 and 18.
   
   

GAS CONNECTION

1. We recommend using only new black iron or  steel pipe. CHECK LOCAL CODES.
2. The gas supply line shall be sized and installed to provide a sufficient supply of gas to meet the maximum demand of the heater without  undue loss of pressure.
3. The sealant used on the threaded joints of the gas pipe must be a type resistant to the action of L.P. Gas. (This sealant should be applied lightly to main threads to ensure excess sealant does not enter lines.)
4. The supply system must include a manual shut off valve and connection in the line, so the heater can be disconnected for servicing. (See  Figure 18).
5. Include a drip leg (trap) and a plugged 1/8” N.P.T. tapping in the line. The tapping should be accessible for test gauge connections upstream of the gas supply connection to the heater.

IMPORTANT:
HOLD THE GAS INLET OF THE APPLIANCE WITH WRENCH WHEN CONNECTING IT TO GAS PIPING AND/OR FITTINGS.
