ELECTRICAL WIRING GAS
All wiring from the SideShot to the appliance must be appropriate Class 1 wiring as follows: installed in rigid metal conduit, inter-
mediate metal conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable, or be otherwise suit-
ably protected from physical damage.
The electrical contact ratings for the diaphragm Fan Proving Switch and High Limit are as follows:
FAN PROVING SWITCH HIGH LIMIT
6.2 Amps (full load) at 120 VAC 10 Amps (full load) at 120 VAC
36 Amps (locked rotor) at 120 VAC 60 Amps (locked rotor) at 120 VAC
The Fan Proving Switch and High Limit are not suitable for loads which exceed the above limits.
SEQUENCE OF OPERATION WITH THE SIDESHOT INSTALLED ON 24 VOLT CONTROLLED GAS APPLIANCES:
As the thermostat/aquastat senses a need for heat, the internal switch of the thermostat/aquastat will close. The switch closure
sends current through the internal controls of appliance (e.g. high limit, low limit and all other safety controls the appliance is
equipped with) and continues to the SideShot Relay/Timer and safety circuit. When the Relay/Timer receives current, the
SideShot motor is energized. After draft is established within the SideShot, the Fan Proving Switch closes completing the circuit to
the 24 volt gas valve. It is important to remember that the electrical interlock of the SideShot is always done at the final signal
which would normally control the gas valve. All thermostats, zones, limits and circulators are to be wired as normally done on a
chimney vented appliance.
All diagrams in this section show the same electrical connections. Follow the diagram which is most appropriate for your installation.
If your appliance gas valve is not labeled TH, TR as outlined in these diagrams, determine the "HOT" and "COM" terminals on the
gas valve and follow the steps outlined on the bottom of Page 15.
