GAS SUPPLY & PIPING

• All gas piping must be installed in compliance with

local codes and utility regulations. In the absence

of local codes the gas line installation must comply

with the latest edition of the National Fuel Gas Code

ANSI Z223.1 or CAN/CGA B149 Installation Codes.

• Some local codes require the installation of a

manual main shut-off valve and ground joint union

external to the furnace. The shut-off valve should

be readily accessible for service and/or emergency

use. Consult the local utility or gas supplier for

additional requirements regarding placement of
the manual main gas shut-off. See

Figure 7 (page

16).

The manifold pressure must be set to the appropriate

value for your installation. Refer to the Manifold

Pressure Adjustment section (

page 18

) for

adjustment instructions.

• Gas piping must never run in or through air ducts,

chimneys, gas vents, or elevator shafts.

• Compounds used to seal joints on gas piping must

be resistant to the actions of LP propane gas.

• The main gas valve and main power disconnect to

the furnace must be properly labeled by the installer

in case emergency shutdown is required.

• An 1/8 inch NPT plugged tap must be installed in

the gas line immediately upstream of the gas supply

connection to the furnace for use when measuring

the gas supply pressure. The plug should be readily

accessible for service use.

• A drip leg should be installed in the vertical pipe

run to the unit (

Figure 7

).

This unit only has right side gas entry. When connecting
the gas, provide clearance between the gas supply line
and the entry hole in the unit’s casing to avoid unwanted
noise and/or damage to the unit. A typical gas service
hookup is shown in

Figure 7

.

Table 15 (page 28)

lists gas pipe capacities for standard

pipe sizes as a function of length in typical applications
based on nominal pressure drop in the line.
