INSTALLATION (CONTINUED)
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 ¾”.
IMPORTANT: The appliance’s venting system should be inspected at least once a year and immediately cleaned if
necessary.
IMPORTANT: THE VENT-AIR INTAKE SYSTEM MUST BE PROPERLY INSTALLED TO INSURE PROPER AND
SAFE OPERATION. THE VENT-AIR INTAKE SYSTEM MUST ALSO BE PROPERLY RE-INSTALLED AND RE-
SEALED TO INSURE 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.
Avertissement: Risque de dommages ou de blessures si les pièces ne sont pas installées conform´ment à ces
schémas et ou si des pièces autres que celles spécifiquement approuvées avec cet appareil sont utilisées.
CAUTION: ALL JOINTS MUST BE AIR-TIGHT.
The venting system consists of: one injected-aluminum cap (A), one vent pipe (B), one vent-air intake pipe (C), one rod
(D), one nut (E), one outdoor mounting plate (F) and one silicon-rubber ring (G). (See figure 14).
Figure 14 Figure 15
1. Measure thickness of the wall as shown in figure 15.
2. If pipes (B), (C) and the rod are long, trim them according to thickness of the wall, as shown in the following table.
3. The hole at the outside of the wall must be a square of 11 ½” (290 mm) x 11 ½” (290 mm). (See figure 17).
4. From the outside of the wall, screw the rod slightly onto support located inside the appliance flue outlet.
5. Slide pipes (B) and (C) through the hole in the wall, and connect them to the appliance flue outlet and air intake,
respectively.
6. The outdoor mounting plate and the silicon-rubber ring should be installed between the vent cap and the exterior
wall. The plate must be positioned flush to the wall and with its standoffs inserted into the wall and sealed with a
non-hardening mastic (silicone caulk). (See figure 17).
Position the outdoor mounting plate so that the vent-air intake pipe has a slight downward slope to the outside. The
downward slope is necessary to prevent the entry of rainwater.

INSTALLATION (CONTINUED)
7. Before attaching the vent cap 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 plate. (See figure 17).
8. Place cap and screw nut “E”, until cap leans against the plate. (See figures 16 and 17).
Figure 16 Figure 17
INSTALLING THE THERMOSTAT SENSOR (MODELS DVEL12 AND DVEL20)
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. Separate the front panel of the appl
iance by removing the
two nuts in the bottom and sliding it up as shown in figure 18.
2.
Place the thermostat sensor under the right bottom of the
bracket and fix it with the same nut that fixes the appliance to
bracket as shown in figures 19 and 20
Figure 18
Figure 19 Figure 20

GAS PIPING
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 21).
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.
Figure 21
WARNING: For L.P.Gas, use PRESSURE REGULATED gas supply. Do not directly connect LP supply tank to the
pressure regulator on the heater. The LP supply tank must have its own separate pressure regulator that can reduce
the supply tank gas pressure down to a maximum of 14 inches (355 mm) of water column pressure.
IMPORTANT: Hold the gas inlet of the appliance with wrench when connecting it to gas piping and/or fittings.
CHECK AFTER GAS CONNECTION
WARNING: All gas piping and connections must be tested for leaks after installation or servicing. All leaks
must be corrected immediately.
1. Make sure the control of the heater is in the “OFF” position.
2. Open the manual shut off valve. Test for leaks by applying liquid detergent to all joints. Check all joints from gas
meter to thermostat gas valve. (Bubbles forming indicate a gas leak)
3. Correct any leak defect at once.

11
GAS PIPING (CONTINUED)
CAUTION: NEVER USE AN OPEN FLAME TO CHECK FOR LEAKS
Pressure testing supply line
ATTENTION: This appliance and its appliance main gas valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi (3,5 kPa).
The appliance must be isolated from the gas supply piping system by closing equipment shutoff valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3,5 kPa).
OPERATION
Read the following instructions carefully (you can also find them on the plates attached to the
heater back):

OPERATION (CONTINUED)
CAUTION
Do not try to adjust heating levels by using the manual shutoff valve.
IMPORTANT
•Do not dry clothes over the heater.
•Do not spray any aerosol near the heater when functioning. Do not store these elements near the appliance.
•Do not touch grill to avoid burns.
•Avoid blocking air inlet and hot air outlet.
•Do not spill water over the heater as it may cause corrosion or damage.
•Do not touch vent cap while heater is operating, to avoid burns.
•If you smell gas, shut off control valve, open doors and windows and do not light any electrical fixture near the
heater. Call your Gas Supplier.
NOTE: It is normal for the new wall furnace to give some odor the first time it is burned. This is due to the curing of the
paint and any undetected oil from the manufacturing process.
It is recommended to burn a new wall furnace for at least two (2) hours the first time that it is used.
CLEANING AND MAINTENANCE
WARNING
Turn off heater and let cool before cleaning.
CAUTION
You must keep control areas and circulating air passageways of heater clean. Inspect these areas of heater before
each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to
excessive lint from carpeting, bedding material, etc.
Verify proper operation after servicing.
S’assurer que l’appareil fonctionne adéquatement une fois l’entretien terminé.
CABINET
Exterior
Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
Air Passageways
