2. Open a faucet in the motor home to relieve
water pressure.
3. Pull the handle of the P-T valve straight out
and allow water to flow until it stops.
4. Let the handle of the P-T valve snap shut.
5. Close the faucet and turn on the water supply
before switching the water heater on.
Manually operate the pressure temperature
relief valve at least once a year.
NOTE: If your water heater is equipped with the
motoraid system, it uses an extension
from the engine cooling system to heat
water in the water heater while driving.
The engine cooling system must also be
cold before opening the pressure-
temperature relief valve. See “Motoraid
Water Heater” for more information.
PROPANE GAS FURNACE
To Start Up
1. Open the Propane Gas Tank valve by turning
fully counter-clockwise.
2. Move the Thermostat/Switch to from OFF to
the desired temperature position.
3. Furnace fan should start to blow immediately
after setting the Thermostat.
4. After approximately 30 seconds, the Furnace
burner should light.
5. The Furnace should now cycle off and on
automatically as the Thermostat demands just
like a household furnace.
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 minutes, ensure
Propane Gas Tank valve is open and tank is not
empty, and repeat Steps 2 through 4.
If the Furnace will not light after three
attempts, follow “Shut Down” steps and contact
your dealer or a local RV service center for
repair.
NOTE: If the Furnace burner has any residuals
of metal protectant or lubricants used
during manufacture of the Furnace, it
may smoke slightly when the Furnace is
used for the first time and may set off
your smoke alarm.
We recommend that you provide
adequate ventilation when using the
Furnace for the first time to avoid a
nuisance smoke alarm.
We do not recommend removing the
smoke alarm battery.
