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 appli-
ance. A knockout is provided at either loca-
tion to allow for the gas pipe installation and
testing of any gas connection.
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 discon-
nected for burner or fan servicing. See gas
specification for pressure details and ratings.
4. When a vertical section of gas pipe is
required for the installation, a condensation trap is needed. See CAN/CGA-B149.1 or .2 for code details.
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.
7. Turn the gas supply ON and check for leaks. DO NOT USE OPEN FLAME FOR THIS PURPOSE. Use an approved leak testing solution.
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).
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.
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.
Important: Always check for gas leaks with
a soap and water solution. Do not use open
flame for leak testing.
