5. Use 2 pipe wrenches when making the connection to the gas valve to keep it from turning.
6. Install a manual shutoff valve in the vertical pipe about 5 ft above floor.
7. Tighten all joints securely.
8. Propane gas connections should only be made by a licensed propane installer.
9. Two stage regulation should be used by the propane installer.
10. Propane gas piping should be checked out by the propane installer.
B. Checking the Gas Piping
After all connections have been made, check immediately for leaks. Open the manual shutoff valve. Test for leaks by applying soap suds (or a
liquid detergent) to each joint. Bubbles forming indicate leak. CORRECT EVEN THE SMALLEST LEAK AT ONCE.
WARNING: Never use a match or open flame to test for leaks. Failure to do so could result in personal injury or death.
The length of pipe or tubing should be measured from the gas meter or propane second stage regulator.
PROCEDURE 7—ELECTRICAL WIRING
WARNING: Turn off electrical power at fuse box before making any line voltage connections. Follow local electrical
codes. Failure to follow this warning could result in electrical shock, personal injury or death.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
All electrical work must conform to local codes as well as the National Electrical Code, ANSI/NFPA 70. In Canada, electrical wiring shall comply
with the Canadian Electrical Codes, CSA C22.1 and .2.
A. Electrical Power Supply
Prior to making any line voltage connections, service switch at boiler should be in the off position and the power turned off at the fuse box.
Run a separate 120 volt circuit from a separate over current protection device in the electrical service entrance panel. This should be a 15-amp
circuit. A service switch has been pre-wired and located on the exterior boiler jacket. See Fig. 17 for diagram showing location of service switch
junction box and power supply connection points. Connect black (hot) lead from the power supply to either of the unused brass screws on the
service switch. Connect the white (neutral) lead from the power supply to the white screw on the service switch. Connect the green (ground) lead
from the power supply to the ground (green) screw on the service switch. The receptacle on the service switch is always powered regardless of
whether the switch is on or off, and could be used as a power supply for an external condensate pump if one is used.
