Gas Line Installation

This gas appliance should be installed by a qualified installer in accordance with local building codes and with current CAN/CGA -
B149.1 or .2 installation codes for Gas Burning appliances and equipment in Canada and the National Fuel Gas Code ANSI Z223 in
the U.S.A.
1. The gas pipeline can be brought in through
either the right or the left side of the appliance.
A knockout is provided at either location to allow
for the gas pipe installation and testing of any
gas connection.

3/8” UNION

2. The gas control inlet is 3/8” NPT. Typical
installation layout for rigid pipe is shown at right.

3. When using copper or flex connector, use
only approved fittings. Always provide a union
so that gas line can be easily disconnected for
burner or fan servicing. See gas specification for
pressure details and ratings.

1/2” X 3/8” SHUTOFF

VALVE

4. When a vertical section of gas pipe is

3/8” NIPPLE

required for the installation, a condensation trap
is needed. See CAN/CGA-B149.1 or .2 for code
details.

1/2” GAS SUPPLY

5. For natural gas, a minimum of 3/8” iron pipe with gas minimum pressure of 4.5” w.c. must be used for supply from the gas meter.
Consult with the local gas utility if any questions arise concerning pipe sizes.
6. A 1/8” NPT plugged tappings are accessible for test gauge connection both on the inlet and outlet of the gas valve.

8. The appliance and its individual shutoff 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 (3.5 KPa).

8. The appliance and its individual shutoff 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 (3.5 KPa).
9. The appliance must be isolated from the gas supply piping system by closing its individual shutoff valve during any pressure
testing of the gas sup- ply piping system at test pressures equal to or less than 1/2 PSIG (3.5 KPa).

testing of the gas sup- ply piping system at test pressures equal to or less than 1/2 PSIG (3.5 KPa).

NOTE:

The gas line connection may be made of 1/2” rigid pipe or an

Approved Kingsman Flex Connector, such as FP15GC

Since some municipalities have additional local codes, it is always best to consult your local authorities and the current CAN/CGA

- B149.1 or .2 installation code in Canada or the National Fuel Gas code ANSI Z223.1 in the U.S.A

Important: Always check for gas leaks with a
soap and water solution. Do not use open flame
for leak testing.

For the state of Massachusetts a T-handle gas
shut-off valve  must be used on a gas
appliance.  This T-handle gas shut-off valve
must be listed and approved by the state of
Massachusetts.  This is in reference to the state
of Massachusetts state code CMR238.
