LEVELING
Use a spirit level to adjust the feet to level the gas steam boiler left-to-right and front-to-back.
GAS CONNECTION
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
A 1"
(2.5 cm) minimum inside diameter gas supply line is recommended. Connect the gas supply to the
gas valve using a 1" to
3
⁄4" (1.9 cm) reducer. Make sure the pipes are clean and free of obstructions.
Codes require that a gas shutoff valve must be installed in the gas line ahead of the boiler.
The burner is equipped with fixed gas and air orifices for use with natural or propane gas.
The gas line must be capable of delivering gas to the boiler without excessive pressure drop at the rate
specified on the rating plate.
The boiler is equipped with a factory preset pressure regulator. No further adjustment should be
required.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds
1
⁄2 psig (3.45 kPa), the gas steam boiler and its individual shutoff
valve must be disconnected from the gas supply piping system.
When gas supply pressure is
1
⁄2 psig (3.45 kPa) or less, the gas steam boiler should be isolated from the
gas supply system by closing its individual manual shutoff valve.
