– 12 –
Where appliance instructions differ from this manual, follow the appliance instructions.
Mount burner in appliance
• Verify appliance burner front plate dimensions and bolt locations.
• Slide gasket supplied with burner over end of air tube.
• Insert burner into appliance opening and bolt in place.
• Level the housing if necessary by loosening the set screws securing the
housing to the air tube. Retighten the set screws.
Inspect components and wiring
• Visually inspect all burner components and wiring.
• Verify that wiring is intact and leads are securely connected.
• Verify that all burner components are in good condition.
• Check gas pressure switch settings. Set the low and high gas pressure
switch settings to +/- 50% of manifold setting.

Gas orifice location
Install gas train on burner
1. The standard burner gas train is shipped fully assembled, with the piping
disconnected at the gas train union. See separate instructions if installing
an optional knocked down gas train. The gas train is available as angled
(standard) or straight (alternate) construction.
2. Connect the gas train at the union (Figure 9).
To avoid damage to gas train components, do not hold compo-
nents with a pipe wrench or overtighten. Use only a crescent
wrench or other means. Failure to comply could result in severe
personal injury, death or substantial property damage.
3. Connect the flexible conduit, pre-attached to the primary control J-box,
to the gas train J-box, and attach the wires to the terminal strip inside
the gas train J-box.
a. Match wire colors of the incoming wires to those pre-wired to the terminal
strip inside the gas train J-box.
b. See the label in the burner junction box or the wiring diagram on page 15.
Gas valve vent opening — If local codes require, install piping
from vent connection to outside, sized and installed per code. A
vent limiting orifice is provided. Install in vent opening, if starts
are hard, before piping vent to outside.
The two-stage regulating diaphragm gas valve on Massachusetts
Code burners uses an interanl bleed, and does not require an
external bleed connection.

Gas train installation
Inspect/redrill gas orifice
If the burner is installed, you must disconnect power to burner
and close main manual gas valve before proceeding. Failure to
do so could result in severe personal injury, death or substantial
property damage.
In the state of Massachusetts, when lever-type gas shutoffs
are used, they must be T-handle type only.
1. Turn off power to the burner/appliance before proceeding.
2. Close main manual gas valve in gas supply line to burner.
3. Disconnect the burner gas train union if the burner/gas train is installed.
See Figures 8 and 9.
4. Locate the correct orifice drill size in Table 1a, page 9 (or appliance
manual). Then check actual orifice size using that size drill bit.
5. If the gas orifice is smaller than required, unscrew the orifice nipple
from the elbow. Then redrill the orifice to the correct size. Replace the
gas train, using only pipe dope listed for use with liquefied petroleum
gases.
6. If the gas orifice is larger than required, remove the orifice nipple from
the elbow. Obtain a replacement orifice nipple. If necessary, drill the
correct orifice hole in the new orifice to the correct size.
7. Replace gas train. Seal pipe joints with a small amount of pipe dope.
Use only pipe dope approved for use with liquefied petroleum gases.
1. Prepare site • prepare burner • mount burner
(continued)
The orifice end of the orifice nipple must face the gas train.
