MINIMUM CLEARANCES

(Replaces pg. 8 in instruction manual)

WARNING

Failure to adhere to these installation and operating instructions may

create a hazard to life and property and will nullify the warranty.

This installation must allow access to the front of the water heater and adequate clearance must be provided for servicing and operating this water heater. The water heater may be installed on either a combustible or noncombustible floor. If the water heater is to be installed directly on carpeting, it must be installed on top of a metal or wood panel (or equivalent) extending beyond the full width and depth of the appliance by at least three (3) inches

(7.6 cm) in any direction or, if the appliance is to be installed in an alcove or closet, the entire floor must be covered by the panel. If the rating plate or the label on the front of the water heater specifies minimum clearances less than those listed in the below table, the water heater may be installed in accordance with the minimum clearances listed on the rating

plate or the label on the front of the water heater.

If it is necessary to install this water heater in an alcove, use the clearances listed in the following table and Figure 1.

BURNER FLAME CHECKS (Replaces pg. 21 of instruction manual)

These models are equipped with self-adjusting air mixture and do not have an adjustable air shutter. At periodic intervals, a visual check of the main burner and pilot flames should be made to determine if they are burning properly. The main burner flame should light smoothly from the pilot. The burner flame should be soft and undefined. After five minutes of burner operation the burner face should be glowing orange and emitting an orange flame.

THE FOLLOWING INSTRUCTIONS ARE FOR INSTALLATION OF:

GAS WATER HEATERS SUITABLE FOR WATER (POTABLE)

HEATING AND SPACE HEATING

(Replaces pg. 28 of instruction manual)

1. All piping components connected to this water heater for space heating applications must be suitable for use with potable water. In

Massachusetts, space heating piping length must not exceed 50 feet.

2. Toxic chemicals, such as those used for boiler treatment, must not be introduced into potable water used for space heating.

3. This water heater must not be connected to an existing heating system or component(s) previously used with a non-potable water heating appliance.

4. When the system requires water for space heating at temperatures higher than required for other means, such as an ASSE approved mixing valve must be installed to temper the water for those uses in order to reduce the scald hazard potential.

Please refer to the illustrations below for the suggested piping arrangement.
