Cold Weather Kit Installation

1) Installation requires the disconnection of the

water lines, gas line, and electrical connections

in the rear of the unit and removal of the unit

from the RV to a bench.

2) First remove the upper tri-panel by removing

(25) screws, unplugging the pressure switch,

ignition control, relay and blower connection,

and lifting off the case, exposing the interior

components.

3)Next lay out the harness with the ground

eyelet at the grounding point with the existing

ground eyelet, the first and second ceramic at the

locations indicated, the pad behind the

modulation valve, and the thermostat close to the

inlet tube grommet.

Kit Includes:

- Heater Assembly # 90296

o Ceramic Clips (2)

o Heater assembly

o Tie Wraps (2 Long, 4 Short)

- Insulation Tape (36”) (Note: must be cut

into 16”, 14” and 4” pieces)

- Instruction

This kit includes the components necessary to

provide protection of the lower extremities of the

water circuit from freezing.

Protection of the heat exchanger (control of the

burner) is accomplished with a low temperature

thermostat which was provided standard on the

unit. It will provide protection for the heat

exchanger to ambient temperatures as low as 15°

This kit is for adding protection of the lower

extremities i.e. the water tubes and the

modulation valve. It operates automatically

when the internal water temperature drops to

38°F.

Thermostat Replacement: (Part must be

ordered separately, # 90311)This switch is

used to light the burner for a limited ignition

cycle of the burner when temperatures dip to and

below approximately 40° F. It is only effective

when the power (12 vdc) is on and the LP tanks

are not turned off during travel or storage. If

there is continuity (switch closed) when the

ambient temperature is above 60° F, it is faulty

and requires replacement.
