GENERAL INSTALLATION
CONSIDERATIONS
When Installing This Product...
1.
Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2.
Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3.
Installer must be a trained, experienced service
technician.
4.
After installation is complete, check out product
operation as provided in these instructions.
WARNING
Remember that liquefied petroleum (LP) gas is
heavier than air and will not vent upward
naturally. Do not light pilot or operate electric
switches, lights, or appliances until you are sure
work area is free of gas. Failure to follow these
instructions may result in an explosion.
CAUTION
1. Disconnect power supply before beginning
wiring to prevent electrical shock or equipment
damage.
2. Turn gas cock to OFF position.
3. On systems with a 24 V valve operator, NEVER
apply a jumper across (or short) the valve coil
terminals, even temporarily. This may burn out
the heat anticipator in the thermostat.
4. NEVER connect a millivoltage operator to
voltage age greater than the operator's rating,
as this may destroy the control.
IMPORTANT
In a millivoltage system, the entire system is
powered by the millivoltage generated by the
Powerpile generator. It is important to clean and
scrape all wires before connecting. Solder and
tape all necessary splices using rosin flux to·
prevent corrosion.Tighten terminal screws
firmly. Total control circuit wiring must not
exceed 30 ft [9 m] of 2-wire, 18 gauge cable or
50 ft [15 m] of 2-wire, 16 gauge cable.
