Operating instructions

B. Chimney Connector and Draft Regulator
Boiler requires 6-in. diameter chimney connector pipe. The draft regulator shipped with boiler must also be used. When properly installed, the
regulator controls the draft automatically. It is best to install it in a horizontal section of the pipe, but it may be in an angled or vertical section.
Make certain that the ″top″ is at top and that the short pipe section which holds vane is horizontal. Install it as close as practicable to boiler. (See
Fig. 12.)
Install chimney connector as follows:
1. Start at boiler with a vertical pipe, at least 1 foot tall, and then an elbow.
2. Install draft regulator making it horizontal.
3. When regulator is in place, start at chimney and work back to regulator.
4. Join the 2 sections with a drawband. The horizontal pipe must slope up toward chimney at least 1/4-in. per ft. It must not leak and must
be firmly supported.
5. Join sections with at least 3 sheet metal screws. Space evenly around the pipe
6. Support every 5 feet with metal straps or stove pipe wire.
C. Minimum Vent Pipe Clearance
Wood and other combustible materials must not be closer than 18-in. from any surface of vent pipe.
PROCEDURE 6—ELECTRICAL WIRING
See Fig. 14 for wiring diagrams for the various models.
A. Installing Thermostat (Not Provided)
The 24-v thermostat location has an important effect on operation of boiler system. BE SURE TO FOLLOW INSTRUCTIONS INCLUDED
WITH THERMOSTAT.
B. Grounding
Permanently ground boiler according to local codes and the current edition of The National Electrical Code. Run a 14 gage or heavier copper wire
from boiler to a grounded connection in service panel or a properly driven and electrically grounded ground rod.
C. Electrcial Power Supply
WARNING: Turn off electric power at fuse box before making any line voltage connections. Follow local electric
codes. Failure to follow this warning could result in electrical shock, personal injury, or death.
All electrical work must conform to local codes as well as the National Electrical Code. If not familiar with wiring and codes in general, have a
competent electrician do this job.
Boiler controls are all wired at the factory. All that is required is to connect a 115-v electric supply and thermostat wires to aquastat relay.
Run a separate circuit from a separate overcurrent protective device in electrical service entrance panel. This should be a 15-amp circuit. Locate
a shutoff switch at boiler. It must be turned OFF during any maintenance. Solder and tape or securely fasten these connections with wire nuts.
