APPLIANCES & INTERIOR FEATURES
5. Close the faucet and turn on the water supply
before switching the water heater on.
Manually operate the pressure temperature re-
lief valve at least once a year. OPERATE THIS
VALVE ONLY WHEN THE WATER HEAT-
ER AND COOLING SYSTEM ARE COLD!
WATER HEATER BY-PASS VALVE
Your coach may be equipped with a water
heater by-pass valve for easier winterization of
water lines using RV antifreeze. The valve is lo-
cated inside the coach near the water heater. See
pg. 7-6 for the exact location in your coach.
Line up the arrow on the handle with the ap-
propriate arrow on the valve plate to either by-
pass or flow through the water heater.
LP GAS FURNACE (SUBURBAN)
Start Up:
1. Open the LP gas tank valve by turning fully
counterclockwise.
2. Move THERMOSTAT switch from Off to
Heat and press the Temp selector button (Up/
Down arrows) until the desired temperature
is shown in the display.
3. Furnace fan will start to blow immediately
after setting thermostat.
4. After about 30 seconds, the furnace burner
will light.
5. The furnace will now cycle off and on auto-
matically as the thermostat demands just like
a household furnace.
.
NOTE: If heat does not come out of the heat
ducts after a minute or so the burner is
not lit. Turn thermostat off for 3-5 min-
utes, check to be sure tank valve is open
and tank is not out of fuel, then try steps
2-4 again. If it still will not light after
three attempts, go to Shut Down steps
and contact your dealer or a local RV
service center.
NOTE: Metal coatings used during manufacture
of the furnace burner parts may smoke
when the furnace is used for the first
time, which may also set off your smoke
alarm. If this happens, provide adequate
ventilation of the smoke to avoid a nui-
sance smoke alarm at this time. We do
not recommend removing the smoke
alarm battery. If it were inadvertently left
disconnected, the smoke alarm would be
inoperative and could not warn you of
impending danger.
Leave by-pass valve handle in NOR-
MAL FLOW position if draining
water and blowing out water lines.
Place in BYPASS position ONLY
when using antifreeze solution in
water lines.
