Mounting Base Feet to Floor

1.Remove front panel (see Removing Front Panel of Heater, page 9).

2.Position heater with base feet in desired location. Mark holes for drilling. Remove heater with base.

3.For carpeted floors, make a small cut with a sharp knife at marked locations prior to drilling. If mounting base to a wood floor, drill 1/8" diameter hole, 3/4" deep. (Do not use anchors in wood floors).

If mounting base to a concrete floor, drill with 1/4" diameter concrete drill bit, 13/8" into floor. Insert anchors completely into holes.

4.Reposition heater with base feet over holes. Secure base to floor with wood screws. See Figure 13.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualified service personmustconnectheatertogas supply. Follow all local codes.

WARNING:Fornaturalgas,never connect heater to private (non-util- ity) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: For natural gas, check gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5" of water. If gas line pressure is higher, heater regulator damage could occur.

CAUTION: For propane/LP gas, never connect heater di- rectly to the propane/LP supply. This heater requires an external regulator (not supplied). Install theexternalregulatorbetweenthe heater and propane/LP supply.

For propane/LP gas, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of water. If you do not reduce incom- ing gas pressure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure

14.Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

Typical Inlet Pipe Diameters

16-18,000 Btu/hr models - 3/8" or greater

26-30,000 Btu/hr models - 1/2" or greater

Installation must include equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 15, page 12).
