Instructions for Installation (cont'd)

Filling the Water Heater

&CAUTION

Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow

from the hot water faucet before turning "ON" gas to the water heater.

To fill the water heater with water:

Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater,

Open the cold water supply valve to the water heater.

NOTE:The cold water supply valve must he left open when the water heater is in use.

To insure complete fdling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run

until a constant flow is obtained. This will let air out of the

water heater and the piping,

Check all new water piping for leaks. Repair as needed.

For proper venting in certain installations, a larger diameter

vent pipe may be necessary. Due to great variances in installa- tions, unforeseeable by the manufacturer of the water heater, you must consult your gas company to aid you in determining the proper venting for your water heater from the vent tables in the latest edition of the National Fuel Gas Code ANSI

Z223.1, also referred to as NFPA 54.

Check the venting system for signs of obstruction or deterio- ration and replace if needed.

The combustion and ventilation air flow must nor be obstructed.

[ &WARNING ]

I_Obstructed or deteriorated vent systems may pres- lent a serious health risk or asphyxiation.
