Improper installation, adjustment, alteration, service

or maintenance can cause property damage, personal

injury or loss of life. Installation and service must be

performed by a licensed professional installer (or

equivalent), service agency or the gas supplier.

WARNING

Do not store combustible materials, including gasoline

and other ammable vapors and liquids, near the

furnace, vent pipe, or warm air ducts. The homeowner

should be cautioned that the furnace area must not

be used as a broom closet or for any other storage

purposes. Such uses may result in actions that could

cause property damage, personal injury, or death.

WARNING

The installation of the furnace, wiring, warm air ducts, venting, etc. must conform to the requirements of the National Fire

Protection Association Standard for the Installation of Oil Burning Equipment, NFPA No. 31; the National Electrical Code,

ANSI/NFPA No. 70 (in the USA); the Installation Code for Oil Burning Equipment, CSA Standard CAN/CSA B139 (in

Canada); the Canadian Electrical Code Part 1, CSA 22.1; the Recommendations of the National Environmental Systems

Contractors Association; and any state or provincial laws or local ordinances. Local authorities having jurisdiction should

be consulted before installation is made. Such applicable regulations or requirements take precedence over the general

instructions in this manual.

CAUTION

Never burn garbage or paper in the heating system and

never leave rags, paper, or any ammable items around

the unit.

CAUTION

This furnace is not approved for installation in a mobile

home. Do not install this furnace in a mobile home.

Installation in a mobile home could result in actions that

could cause property damage, personal injury, or death.

Close disconnect switch A. Basement - Open Enclosed* B. Utility Room - Open Enclosed* B. Set thermostat to call for heat C. Bleed air from lines and pump; run for 20 seconds after bubble disappears C.

Installation WARNING Read all instructions before starting work so installation will conform to Underwriters’ Laboratories or Canadian Standards Association requirements. The furnace must be level when placed on its foundation (upflow, counterflow, and basement models) or in its suspended position (horizontal models). Using a carpenter’s level, check the furnace in at least two directions. The weight must be distributed evenly before the duct work is attached.
PAGE 4
If the furnace is installed in a space within a building of tight construction, air must be supplied from outdoors. In this case, one opening shall be within 12” of the ceiling and the other within 12” of the floor. If vertical combustion ducts are run, each opening must have a free area of at least 1 square inch per 4000 BTU per hour. If horizontal combustion ducts are run, 1 square inch per 2000 BTU per hour of the total input of all appliances is required.
PAGE 5
Vertical Venting 1. Local building codes may have more stringent installation requirements and should be consulted before installation of the unit. 2. The flue pipe should be as short as possible to do the job. 3. The flue pipe should not be smaller than the outlet diameter of the flue outlet of the furnace. 4. Single wall flue pipe should not run outside or through any unconditioned space. 5. The chimney should terminate 2’ above the highest peak of a peaked roof, and 3’ higher than a flat roof.

or restriction, leakage, corrosion, or other deficiencies which could cause an unsafe condition. 3. 4. 5. 6. 7. Insofar as is practical, close all building doors and windows between the space in which the appliances remaining connected to the common venting system are located and other spaces in the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed.

To enable the continuous blower operation, place the fan switch on the thermostat into the ON position. A call for fan from the thermostat closes R to G on the blower interface board. The control waits for a 1-second thermostat debounce delay before responding to the call for fan by ramping the circulating blower up to 50% of the cooling speed. When the call for continuous fan is satisfied, the control immediately ramps down the circulating blower.

ADJUST*, HEAT, and COOL Taps ADJUST (on Blower Interface Board) NORM (+) (–) TEST * Placing ADJUST jumper plug in the TEST position energizes the motor to a default factory setting. This can be used to determine if the motor is operating properly. Test pin function is enabled during any mode of thermostat call. If no thermostat call is present, test function is disabled. The ADJUST jumper plug must be returned to original position after testing procedure is completed.
PAGE 10
Burner Adjustment All adjustment to this furnace and its components must be done by a qualified service technician. Refer to Table 2 for nozzle and pump pressure information. 11. Use the CO2 reading and the flue gas temperature reading to determine unit efficiency. 12. When the proper combustion and smoke readings have been achieved, tighten the air shutter screw(s) and air band screws that were loosened in Step 5.

Operation y Y 7.5 minutes Sequence of Operation 100% 82% 1 min 82% Heating See Figure 8. The thermostat calls for heat, activating the burner motor. After a 15-second pre-purge period, power is sent to the burner and ignition is established. When the burner pump reaches full speed, the solenoid valve is energized. After the thermostat is satisfied, the thermostat circuit opens. The solenoid valve is de-energized before the pump rotation stops.

toward the rear of the heat exchanger to clean out the crossover tube; replace the locking screw and cap on the inspection tube. Continuous Fan See Figure 11. When the thermostat is set for continuous fan operation and there is no demand for heating or cooling, a call for fan closes the R to G circuit and the circulating blower motor runs at 50% of the selected cooling CFM until switched off. G 5. Do not attempt to clean the combustion chamber, as it can be easily damaged. 6.
