7. Check that all wire connections are firmly in place and there are
no signs of chafing or cracks on the insulation. Verify that the
spark ignition cable between the Control Board and the igniter
is securely in place and not shorted to any metal component.
11. A sealing ring is assembled on the chimney. (Fig. 34)
Inspect to make sure the seal does not have any
cracks or breaks, and that it is in good condition.
Contact Furrion for replacement.
NOTE: When installing the seal, make sure the words
“INSIDE” are facing inward.
Filter Cleaning
There is a filter screen on the Water Heater inlet water line
connection. The filter screen needs to be cleaned periodically
to prevent blockages from forming. Follow below steps below
to clean the filter (Fig. 35) :
1. Step 1: Open the door of the
Water Heater, remove the bae.
2. Step 2 : Unscrew the filter cover by hand
or a proper tool counter clockwise.
3. Clean the screen filter by flushing any
debris accumulated.
Burn or Scald Hazard
• Never actuate the pres-
sure relief valve while the
appliance is in operation.
• Never tamper with the
pressure relief valve.
8. Inspect the pressure safety valve to ensure
it has not been leaking (no water residue).
See “Pressure Safety Valve Maintenance”
for further inspection. (Fig. 32)
9. Inspect/clean/replace water inlet filter as
necessary, see “Filter Cleaning” section.
10. 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 removing the water
heater door and bae to observe the flames by looking at
the burner under the edge of the heat exchanger. (Fig. 33)
