PLANNING

Planning the installation is an important first step: it will save time and money later in the actual installation. In planning the installation, consider:

1. Where the heater will be located.

This heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure equal to or less than 1/2 psig (3.45 kPa).

2. All components needed to complete the

project.

'..,:,..' The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa).

HIGH ELEVATION DERATING

Input ratings are shown in BTU per hour and are for elevations up to 4,500 (1370m) feet.

For elevations above 4,500 (1370m) feet, ratings should be reduced at the rate of four (4) percent for each 1,000 feet above sea level.
