Other hardware required to complete the installation of the gas supply line will include a manual shutoff valve, a sediment trap (drip leg) and a ground-joint union. A pressure regulator valve may also be required (to convert gas pressure from pounds to inches of pressure). The manual shutoff valve must be located within 6-ft (1.83 m) of the unit. The union, located in the final leg entering the unit, must be located at least 9-in (230 mm) away from the access panel to permit the panel to be removed for service. If a regulator valve is installed, it must be located a minimum of 4-ft (1220 mm) away from the unit’s flue outlet. Some municipal codes require that the manual

shutoff valve be located upstream of the sediment trap. See Fig. 18 and Fig. 19 for typical piping arrangements for gas piping that has been routed through the sidewall of the curb. See Fig. 20 for typical piping arrangement when thru-base is used. Ensure that all piping does not block access to the unit’s main control box or limit the required working space in front of the control box.

When installing the gas supply line, observe local codes pertaining to gas pipe installations. Refer to the NFPA 54/ANSI Z223.1 NFGC latest edition (in Canada, CAN/CSA B149.1). In the absence of local building codes, adhere to the following pertinent recommendations:

1. Avoid low spots in long runs of pipe. Grade all pipe

1/4-in. in every 15 ft (7 mm in every 5 m) to prevent

traps. Grade all horizontal runs downward to risers.

Use risers to connect to heating section and to meter.

2. Protect all segments of piping system against physical

and thermal damage. Support all piping with appro-

priate straps, hangers, etc. Use a minimum of one

hanger every 6 ft (1.8 m). For pipe sizes larger than

1/2-in., follow recommendations of national codes.

3. Apply joint compound (pipe dope) sparingly and only

to male threads of joint when making pipe connec-

tions. Use only pipe dope that is resistant to action of

liquefied petroleum gases as specified by local and/or

national codes. If using PTFE (Teflon) tape, ensure

the material is Double Density type and is labeled for

use on gas lines. Apply tape per manufacturer’s in-

structions.

4. Pressure-test all gas piping in accordance with local

and national plumbing and gas codes before connect-

ing piping to unit.
