10. Fasten door and vent with 10 screws provided or equivalent type.
FLUSH DOOR INSTALLATION
To prevent moisture from entering inside of coach, apply RTV
type sealant to all sealing areas.
The door bezel must fit tightly, to prevent water leakage.
Doors are designed to allow water drainage in either horizontal or
vertical installations. Proper location of vent assembly is important
for proper exhausting of fumes and proper function of furnace.
NOTE: RTV type sealant must be applied to the bezel and casing
at the bottom right side to prevent possible water wicking into the
coach. See drawing for areas that must be sealed once bezel is in
place.
1.
Locate and cut opening in side wall where unit will be installed.
2.
Flush mounted door systems require that the furnace be installed
on a 1" high platform for the door cutout to be level with the floor
surface. If not the sidewall can be routed out across the bottom to
the depth of the bezel to create a pocket area.
3.
Apply RTV type sealant to entire back flange of bezel creating a
complete seal.
4.
Secure bezel by inserting bezel into wall cutout and securing
through the 10 mounting tabs to the side wall framing. Make sure
that the bezel is tight against the exterior side wall.
5.
Connect the gas line to the valve and push the gas line plug into
casing opening.
6.
The door bezel must fit tightly against the exterior sidewall to
prevent water leakage.
7.
Remove excess sealant from around bezel and visually inspect
bezel to make sure it is completely sealed.
8.
Secure furnace with mounting legs provided.
9.
Connect the electrical wiring see wiring section.
10. Fasten door and vent with 6 screws provided.
HARD DUCT SYSTEMS
When designing hard duct systems:
Undersized ducting will cause high temperature limiting.
Oversized ducting will cause inadequate air flow from registers.
When hard ducting is 1-1/2" in depth, an additional flex duct may
be needed to maintain air flow requirements.
DO NOT install floor registers within 2 feet of return air openings.
See ducting option from casing top and bottom areas. Hard
ducting must be sealed to the furnace and floor to insure proper
operation of the appliance.
Units can be installed as bottom discharge systems in either
horizontal or vertical position.
FLOOR DISCHARGE CUTOUTS
1.
Remove bottom discharge plate or side, these ducting option
must be connected to a floor ducting system.
2.
The drawing shows the use of a gasket and plenum plate for
attaching furnace to the flooring. See parts list for order number.
3.
Other methods of sealing furnace to the floor are acceptable as
long as clearances and seals meet requirements of clearances
and temperature.
4.
Fasten plenum plate bend tabs over floor cutout. (If a gasket and
plenum plate is not used seal furnace to hard ducting system with
approved tape making sure seal is airtight) Continue with step 5.
5.
Position gasket on plenum over opening.
6.
Set furnace on gasket; make sure gasket remains in position.
7.
Additional flex ducting can also be used to maintain correct static
pressure.
FIRE OR EXPLOSION
Never check for leaks with an open flame. Turn on the gas and apply
soapy water to all joints to see if bubbles are formed.
GAS CONNECTION
Propane Gas Pressure Test
The furnace and any individual shut-off valve must be
disconnected from gas supply piping system during pressure
testing of system at test pressures of more than 1//2" PSI.
Before furnace is connected, piping systems are to be tested to
be leak free. The test must maintain air pressure of a least 6" of
mercury or 3 PSI for at least 10 minutes.
The entire piping system is to be adjusted to maintain a pressure
of 10" to 13" W.C. when all appliances are in operation.
Test gas connections for leakage with soapy water or a leak test
solution.
If local codes allow the use of a flexible gas appliance connector,
always use a new listed connector. Do not use a connector which
has previously serviced another gas appliance.
1.
Connect gas line to the fitting located on the valve through hole in
top of casing, or if supplied with an extended manifold at the rear
of the furnace.
2.
Be sure all male pipe threads, other than flare fittings, are treated
with a sealing compound resistant to chemical reaction of
propane (LP) gas. DO NOT put sealing compound on flare fittings
3.
Remove grommet plug from furnace. After inserting gas line
through grommet plug and connecting to valve re-install grommet
plug, this is a required air seal. (DO NOT CUT)
4.
Connect gas line inside furnace casing immediately ahead of gas
control valve or at the rear when extended manifold is supplied.
5.
Use two wrenches to hold brass fitting and flare nut when
tightening gas line to brass fitting. DO NOT twist valve assembly,
torque fitting to 20-22 ft. lbs.
