GSW 72090 manual Gas Supply, Failure to Properly Install this Heater MAY, Result in a Fire Hazard

Page 7

The 60 gallon heater is equipped with a Heat Reflector Shield (see Figure 2). This Shield reflects heat from the High-input heaters to prevent damage to combustible floors. The Shield is held in place by three (3) tabs that rest on the inside of the legs of the water heater. Ensure the Shield is positioned horizontally (parallel to the bottom of the heater) and in the designated position of 38mm (1.5 in.) below the flame-arrester.

ventilation systems, clothes dryers, fireplaces, etc., can affect the proper operation of the water heater. Special attention must be given to conditions these devices may create. Flow reversal of flue gases may cause an increase of carbon monoxide inside of the dwelling, as shown in Figure 7.

If the water heater is located in an area that is subject to an excessive amount of lint, dirt or oil, it may be necessary to clean the flame arrester periodically (see “Maintenance” section).

Important: It is always recommended that a suitable drain pan be installed under the water heater to protect the area from water damage resulting from normal condensation, a leaking tank or piping connections. Refer to Figure 1. Under no circumstances is the manufacturer to be held responsi- ble for any water damage in connection with this water heater.
