ROUTINE MAINTENANCE
We recommend that the GSWH-1 water heater be inspected regularly by the user and at least
once a year by a qualified service technician.
Before an inspection make sure that the LP Gas and Water supply are connected and turned on.
A routine inspection must include the following items:
1.
Inspect the integrity of the sealing (caulking or tape) between the side wall and the door
of the water heater and make sure that the unit is solidly mounted to the vehicle.
2.
Verify that the air inlet openings (louvers) are completely open and clear of any debris
including mud, leaves, twigs, insects etc. Remove all obstructions to allow full air flow.
3.
Inspect the Exhaust tube and make sure that it is also unobstructed and that the Exhaust
screen is clean.
4.
Open the cover and verify that no debris or extraneous combustible materials are present
anywhere (especially in the area of the burner and the gas controls); remove any item
present and wipe clean the bottom of the housing.
5.
Inspect the interior surface of the housing for any cracks or corroded areas that could
allow penetration of gases into the interior of the vehicle. Check especially around the
Hot Water, Cold Water, Gas and electrical connections.
6.
Check that all wire connections are firmly in place and there are no signs of chafing or
cracks on the wire insulation. Note that the spark ignition cable between the Circuit
Board and the igniter is securely in place and not shorted to any metal component.
7.
At least once a year activate the Relief Valve by lifting the lever on top of the valve.
MAKE SURE THAT THE WATER HEATER HAS NOT BEEN ON RECENTLY AND THE
HOT WATER OUTLET IS COLD.
8.
Turn on the power to the water heater and open a hot water faucet to inspect the flame
of the burner. The flame should be of the normal bluish appearance that indicates proper
combustion. This can be accomplished by observing the flames through the sight hole
and looking at the burner under the edge of the heat exchanger (See Figure 9.).
