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.

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 pro-

vide a union so that gas line can be easily disconnected for burner or fan servic-

ing. See gas specification for pressure details and ratings.

4. When a vertical section of gas pipe is required for the installation, a condensa-

tion 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 pres-

sures 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 supply piping sys-

tem 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 flex connector. 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.
