Note: This is not an original OEM part and it should not be used as a warranty replacement.
Note: Suggested alternate to Atwood Hydroflame 1017 or 31017 relay.
This relay is a suggested alternate per original manufacturer of relay. The 12v Hydroflame part is replaced with a 24v relay. This relay will look different & will have double the terminals on it.
The wiring for this relay will be 12v positive (usually red) on top terminals & the motor & limit switch wiring on the bottom (wire color may vary). Since this has double the terminals, you must make sure that the wires are directly across from the other & not criss crossed.
It is also larger than the original & will mount on the side of the unit. The two-sided gasket included in the package is to help with installation. When installing this item in place of the 31017 Hydroflame relay, the wiring is as follows: blue and yellow wires go to the bottom terminals and the reds go to the top.
The relay may take up to 3 minutes to operate fan after thermostat is set for heat, and relay will shut off fan with in 15-seconds after thermostat is satisfied.
THANKS FOR LOOKING!
