MAKING GAS CONNECTIONS
The unit is factory equipped with a 3/8” NPT gas connection. The size of the pipe should be computed according to the type of gas and the
length of the run. Table 2 gives a reasonably accurate size for the service line. The quantities given in the table are for cubic feet per hour.
To convert BTU capacity to cubic feet, divide total BTU load by the BTU value of the gas being used. The table is for natural gas only. To
convert to liquefied petroleum (LP) gas, multiply by .633. The pressure drop caused by other gas appliances being served by any portion
of the line provided for this installation must be considered. If the new line is takeoff from an existing line to another appliance, pressure
drop computation with the table must include the demand of the other appliance.
CAUTION
Suburban Applied Products does not recommend the use of flex tubing to make the gas connections to the unit unless the
flex tubing is a high quality stainless certified by AGA and approved for use by local code.

OPERATING PRESSURE
All units for burning natural gas are equipped with a valve having a built-in regulator preset at 3.5” W.C. pressure. All units for burning
liquefied petroleum (LP) gas are equipped with a valve having a built-in regulator preset at 10.5” W.C. pressure. Do not adjust the
regulator set screw on the valve. Over firing of the unit may occur.
It is recommended that the installer install a manual shut-off valve in the gas supply line to the unit. It is also recommended that a ground
joint union be installed between the unit and this shut-off valve.
A condensate trap should also be installed in the gas supply line as close to the unit as possible.
In order to maintain a check on gas supply pressure to the unit, Suburban advises the installer to provide a 1/8” NPT plug tap for test
gauge connection immediately upstream of the gas supply connection to the unit.
The unit and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the gas
system at test pressures in excess of 1/2 PSIG. The unit must be isolated from the gas supply piping system by closing its individual
manual shut-off valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 PSIG.
WARNING
A pipe thread compound resistant to the action of liquefied petroleum (LP) and natural gas must be used on all pipe joints.
All gas piping should be tested with a soap and water solution to assure gas-tight connections.
WARNING
Do not use an open flame to check for leaks!
MAKING ELECTRICAL CONNECTIONS
(208 - 230 Volts)
If local codes permit, the service cord as supplied with the unit may be used. The service cord is added at the factory for testing during
production. If local codes do not permit the use of a service cord, it must be removed and the electrical connections made in the junction
box.
