Fixed Adjustment Main and Pilot Regulators

37C72U

Water Heater Thermostat Control

Installation Instructions

(Left-Hand Outlet Thread Model)

FOR LP GAS ONLY

FOR YOUR SAFETY

“WHAT TO DO IF YOU SMELL GAS”

•Do not try to light any appliance.

•Do not touch any electrical switch; do not use any phone in your building.

•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

!WARNING

Do not use this LP Gas control on a Natural Gas water heater. Improper operation could occur, re- sulting in personal injury and/or death due to Car- bon Monoxide poisoning, fire, or explosion. Check for proper gas type as listed on the rating plate affixed to the water heater.

NOTE

The main and pilot gas regulators require no field service. They automatically control and maintain the outlet main and pilot burner gas pressure.

This gas control is equipped with LEFT-HAND threads in the outlet for use on LP gas water heaters where the connection between the gas control and the main burner manifold are with LEFT-HAND threads.

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PROPERTY DAMAGE, PERSONAL INJURY AND/OR DEATH.

1.This control must be installed or serviced only by a professional.

2.Do not use force when moving the gas control knob. If you cannot turn the knob with hand pressure only, the control must be replaced.

3.Do not use the control if the knob will not “pop up” after being depressed while the knob is in the PILOT posi- tion. The mechanism is damaged and the control must be replaced. Shut off gas to the water heater.

4.For your safety, this control is supplied with tamper resistant screws. Do not attempt to repair or adjust the control. If you experience problems, replace the control immediately. Continuing to use a damaged control could result in fire and/or explosion.

5.LP gas is heavier than air. Leaking gas will settle near the ground and will tend to accumulate.

6.An odorant has been added to the gas to help you detect it. Before lighting, search for the odor of gas by sniffing at floor level around the water heater.

7.In some situations, the gas may lose its odor. To detect unodorized gas, you must have a gas detector which can be purchased from your gas company. If you do not have a detector and have the slightest suspicion that gas may be present, get out of the house and call the gas company. DO NOT RELY TOTALLY ON YOUR NOSE.

8.If any problems or questions are encountered about the safe use of LP gas, contact your local gas supplier.

!WARNING

Scald burns occur in under one second with 160° water, which this thermostat will deliver if the temperature dial is set at “VERY HOT”. Lower settings of the temperature dial will reduce the risk of scald and will reduce your fuel bill.
