Gas Connection, Typical Gas Line Connection

Gas Connection

Check Gas Type. Use only the gas type indicated on the heater’s rating plate. If the gas type indicated on the plate is not your type of gas supply, DO NOT INSTALL. Contact your dealer for the proper model.

WARNING

DANGER OF PROPERTY DAMAGE,

BODILY INJURY OR DEATH.

Make sure the heater is equipped to operate on the type of gas available. Models designated as natural gas are to be used with natural gas only. Heaters designated for use with liqueﬁed petro- leum (l.p.) gas have oriﬁces sized for commercial- ly pure propane gas. They cannot be used with butane or a mixture of butane and propane.

Gas Piping. The gas supply line must be of an adequate size to handle the BTU/HR requirements and length of the run for the unit being installed.

Determine the minimum pipe size from the piping size chart on Page 12. The normal gas connection at this appliance is 1/2” NPT made at the left of the unit.

Always use an external regulator for all LP installations to reduce the supply tank pressure to a maximum of 13” w.c. This is in ad- dition to the regulator ﬁtted to the heater.

All piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANSI Z223.1/NFPA 54), whichever applies.

WARNING: Connecting directly to an unregulated LP tank can cause an explosion.

Gas Connection. If installation is for L.P. gas, have L.P. in- staller use two-stage regulation and make all connections from storage tank to heater. Refer to the National Fuel Gas Code for the proper supply tank size with the Btu’s/Hr requirements. If this is the ONLY gas appliance, we recommend a minimum 200 pound cylinder with a ﬁll gauge. Use of a 100 pound cylinder is not recommended. Other household gas appliances may require the tank size to be larger.

Use two pipe wrenches when making the connection to the valve to prevent turning or damage to gas valve or regulator.

Connection between the manual shut-off valve and the gas valve can be made with a CSA design certiﬁed ﬂexible connec- tor if allowed by local codes. A 10 inch, 1/2” NPT listed stain- less steel ﬂexible connector is supplied with the gas log heater. Tighten all joints securely.

CAUTION: Failure to install a drip leg (sediment trap) may result in improper combustion that will produce soot. Reference Sections 3.7 and 5.5.7 and Figure 5.5.7 of the National Fuel Gas Code for guidance.

Typical Gas Line Connection

Step 1: With the engine assembly free from the ﬁreplace, check tightness of ﬂexible connector ﬁttings.

CAUTION: Use one wrench to hold the valve and one wrench to loosen and tighten the brass adapter and the ﬂex line connection. Failure to hold the valve while loosening and tightening the ﬁttings can damage the unit and cause gas leaks.

Step 2: Set the engine assembly into the ﬁreplace and connect the ﬂexible connector to the gas piping that has been installed per local codes, or in the absence of local codes, ANSI Z223.1/ NFPA 54 latest edition.

Step 3: After the last connection is made, screw the engine as- sembly to the bottom of the ﬁreplace. (Fig. 3)

Step 4: Test all connections on the unit and piping for gas leaks.

Testing the Gas Piping. Test all piping for leaks. When check- ing gas piping to the heater with gas pressure less than 1/2 PSI, shut off manual gas valve for the heater. If gas piping is to be checked with the pressure at or above 1/2 PSI, the heater and manual shut off valve must be disconnected during testing to prevent damage to the regulator on the unit, (see warning below).

WARNING

DANGER OF PROPERTY DAMAGE,

BODILY INJURY OR DEATH.

Never use a match or open ﬂame to test for leaks. Never exceed speciﬁed pressures for testing. High pressures may damage the appliance regulator which would re- quire replacement. Liqueﬁed petroleum (L.P.) is heavier than air and it will settle in any low area, including open depressions and it will remain there unless area is ven- tilatedNever attempt start-up of unit before thoroughly ventilating area.A.

WARNING: Be sure that the gas type indicated on the gas log rating plate concurs with the gas system in your building.

To ensure that the gas lines and connections do not have any leaks, a pressure test should be performed. Only a qualiﬁed installer should perform the pressure test to ensure that the unit is not damaged by high pressures!

If you connect natural gas to an LP gas unit, you may be un- able to ignite the pilot. If the pilot does ignite, the front burner ﬂame on the low setting will be bright blue but only 1/4” to 1/2” long and most likely lifting off the burner ports. If this is the case, turn the unit off immediately and contact the dealer where the unit was purchased.

If you connect LP gas to a natural gas unit, the front burner ﬂame on the low setting will be about 6” - 8” long. On the medium and high setting, the front burner ﬂames will be bright yellow and about 10” in length. Turn the unit off immediately! If the unit is allowed to run in this condition, substantial amounts of soot will be generated and emitted into the house. Contact the dealer where the unit was purchased.
