underneath the smoke box (rear of unit), tilt one side of unit just high enough to lift lugs out of holes in skid, then knock skid out from underneath unit. Then do the same thing on the other side of unit. THE UNIT IS NOT BOLTED TO THE SKIDS. The 3/4" lugs welded to the unit simply fit into the 3/4" holes in the skids.

IMPORTANT

DO NOT TILT UNIT BY PUSHING AGAINST JACKET

IT IS NOT NECESSARY

AND BY DOING SO THE JACKET WILL BE DAMAGED

LEVELING UNIT

In case floor is uneven, unit may easily be made level by inserting shims under the 4 shipping lugs. These lugs also keep the jacket 1/2" off the floor, protecting it from wet floors and dampness.

PIPING AND WIRING

Once the unit is in its proper location with the packing carton, skids and packing material removed, it is ready for piping and connection from Room Thermostat and 110 V. 60 Cy. A.C. Current.

CONTROL SYSTEM

The controls furnished are for a one zone Forced Water System consisting of T87F Room Thermostat, L8124A-1007 Triple Acting Aquastat and Circulator Relay, C554A-1018 Cadmium Photocell, R8184G-1005 Burner Relay and V4046A-1009 Oil Valve. Description and complete wiring diagram will be found packed with each control.

SPECIAL CONTROL SYSTEMS

For special control systems such as multiple installations, zone controlled, unit heater, radiant panel, etc., write to factory for wiring diagrams.

CHIMNEY AND BREECHING REQUIREMENTS

The CP boiler should be connected to a vertical vent system that will prevent: (1) positive pressure in the flue, (2) backward flow of flue gas through the unit when the burner stops, and (3) condensation in the flue.

Use double-walled or insulated pipe for sections of the flue in cold areas. All outside vents, except for short extensions, must be insulated to avoid condensation in the flue. Several types of prefabricated chimneys are available providing double-walled or insulated pipe, some with ceramic and others with metallic liners.

While the unit is equipped with an induced draft fan, proper size vent must be provided to remove the gases of combustion. It is recommended that a 4" to 5" increaser be used for venting the 87CPO and 108CPO and a 4" to 6" increaser be used for the 128CPO. For abnormal runs (exceeding 10 ft.), consult factory.

Vent and breeching must be gas tight by sealing with asbestos or thermo-setting pressure sensitive tape.

DRAFT REGULATOR

It is recommended that a draft regulator be installed in chimney flue just below the flue pipe opening, if the unit is attached to an extremely high chimney; an unlined chimney; or a chimney which is constructed on the exterior of the house.

CONTROLS AND TRIM

Controls are installed in place at the Factory. Attach thermo-altimeter in 1/2" tapping in top front of boiler. Install 3/4" × close nipple in 3/4" top connection with 3/4" × 3/4" × 1/2" Tee. 3/4" Tee opening for installation of the relief valve and 1/2" opening for expansion tank.

WIRING

Controls are all in place and wired at the factory except connection to circulator.

REGULATING OIL PRESSURE

Standard nozzles furnished with the burner will produce the stamped rated capacity when used with Commercial Standard No. 2 Fuel Oil, and operated with a pressure of 100 lbs. per square inch. The standard setting of the fuel unit is 100 lbs. Due to difference in tank elevations, the pressure should be adjusted at the time of start up.

FUEL LINES

Care should be employed when attaching the oil lines to the fuel unit. Overtightening or twisting will twist the pump-motor mounting plate and
