INSULATION BLANKETS

Insulation blankets available to the general public for external use on gas water heaters are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank water heaters. Your Water heater meets or exceeds the National Appliance Energy Conser- vation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.

Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 1 for identifica- tion of components mentioned below). Failure to follow these instructions can restrict the air flow required for proper combus- tion, resulting in fire, asphyxiation, serious personal injury or death.

•Do not cover the outer door, thermostat or temperature & pressure relief valve.

•Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.

VENTILATION FOR APPLIANCES LOCATED IN CONFINED SPACES

FIGURE 3

Confined Space is a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input rating of all appliances installed in that space.

VENT TERMINATION

Before installing water heater determine placement of vent ter- mination.

Make certain to observe vent location limitation, see Figures 3, 4 & 12.

Minimum clearances between the water heater and combustible and noncombustible construction are: 0mm (0 in.) from sides, 0mm (0 in.) from back, 102mm (4 in.) from front of jacket to closet door and 508mm (20 in.) from top of jacket to combustible and noncombustible material. Minimum vent clearance: 25mm (1 in.)*. Provide 915mm (3 ft.) front clearance for servicing and adequate clearance between the jacket top & ceiling for servicing the flue area, see Figure 4.

*Where the wall is combustible and the wall thickness is over 356mm (14 in.), 25mm (1 in.) clearance to combustible materials around the vent terminal is needed. The first 356mm (14 in.) is zero clearance.

Make certain the vent locations comply with the “Natural Gas and Propane Installation Code” CAN/CSA-B149.1 and/or lo- cal codes. There is some important information shown in Figure 12.

For a second or more direct vent unit, the distance between vent terminals must be a minimum of 305mm (12 in.).
