IMPROPER INSTALLATION MAY CRE- ATE A CONDITION WHERE THE OP- ERATION OF THE PRODUCT COULD CAUSE PERSONAL INJURY OR PROPERTY DAMAGE.
IMPROPER INSTALLATION, ADJUST- MENT, ALTERATION, SERVICE OR MAINTENANCE CAN CAUSE INJURY OR PROPERTY DAMAGE. REFER TO THIS MANUAL FOR ASSISTANCE OR ADDITIONAL INFORMATION, CON- SULT A QUALIFIED INSTALLER, SER- VICE AGENCY OR THE FUEL SUP- PLIER.
THIS PRODUCT MUST BE INSTALLED IN STRICT COMPLIANCE WITH THESE INSTALLATION INSTRUCTIONS AND ANY APPLICABLE LOCAL, STATE, AND NATIONAL CODES INCLUDING BUT NOT LIMITED TO: BUILDING, ELECTRICAL AND MECHANICAL CODES.
The furnace area must not be used as a broom closet or for any other storage purposes, as a fire hazard may be cre- ated. Never store items such as the fol- lowing on, near or in contact with the furnace:
1.Spray or aerosol cans, rags, brooms, dust mops, vacuum clean- ers or other cleaning tools.
2.Soap powders, bleaches, waxes or other cleaning compounds; plastic items or containers, gasoline, kero- sene, cigarette lighter fluid, dry cleaning fluids, or other volatile flu- ids.
3.Paint thinners or other painting ma- terials and compounds.
4.Paper bags, boxes, or other paper or cardboard products.
Never operate the furnace with the blower door removed. To do so could result in serious personal injury and/or equipment damage.
DO NOT USE GASOLINE, CRANK- CASE OIL, OR ANY OTHER OIL CONTAINING GASOLINE AS A FUEL FOR THIS FURNACE.
INTRODUCTION
Please read these instructions com- pletely and carefully before installing and operating the furnace.
The furnace must be installed and set up by a qualified contractor.
Model P3DHX12F08001 is an oil fired forced air multi-positional furnace, with an output capacity range of 60,000 BTU/Hr. to 90,000 BTU/Hr. Model P2DHX16F12001 is an oil fired forced air multi-positional furnace, with an output capacity range of 91,000 BTU/Hr. to 128,000 BTU/Hr. These models may be installed in the down-flow position, as well as both horizontal positions.
Model P2LBX16F14501 is a rear-breech lowboy model with an output range of 130,000 to 143,000 BTUH. Model P4LBX20F19001 is a rear-breech low- boy model with an output range of 168,000 to 188,000 BTUH.
All models are listed with the Canadian Standards Association, (CSA), and com- ply with the standards of both the United States and Canada for use with No. 1 (Stove) and No. 2 (Furnace) Oil.
In the United States, the installation of the furnace and related equipment shall be installed in accordance with the regu- lations of NFPA No. 31, Installation of Oil Burning Equipment, as well as in accor- dance with local codes.
In Canada, the installation of the furnace and related equipment shall be installed in accordance with the regulations of CAN/CSA - B139, Installation Code For Oil Burning Equipment, as well as in accordance with local codes.
When installation or application ques- tions arise, regulations prescribed in the National Codes and Local Regulations take precedence over the general in- structions provided with this installation manual. When in doubt, please consult your local authorities.
All P*DHX models are shipped assem- bled, pre-wired, ready for down-flow op- eration. P*DHX furnace models are air conditioning ready. The furnace should be carefully inspected for damage when being unpacked.
The P2LBX16F14501 model is shipped assembled, pre-wired, and ready for lowboy furnace applications. The P2LBX16F14501 model is air condition- ing ready.
The P4LBX20F19001 is shipped in two pieces, a furnace section and a blower section, and must be assembled at the installation site. Some field wiring is re- quired. The P4LBX20F19001 is shipped as a heating only furnace; however, air conditioning may be added with the addi- tion of field-installed controls.
HEAT LOSS
To determine the correct furnace and firing rate for an application, it is neces- sary to calculate the maximum hourly heat loss of the building based on local design conditions. In new construction, the heat loss should be calculated on a room-by-room basis to enable proper sizing of the trunk and branch ductwork. In retrofit applications, a building shell (overall) heat loss calculation may be used.
In the United States, Manual J. titled, "Load Calculation" published by the Air Conditioning Contractors of America, (ACCA), describes a suitable procedure for calculating the maximum hourly heat loss.
In Canada, the maximum hourly heat loss may be calculated in accordance with the procedures described in the manuals of the Heating, Refrigeration and Air Conditioning Institute (HRAI), or by other method prescribed by authori- ties having jurisdiction that are suitable for local conditions.
LOCATION OF UNIT
The furnace should be located such that the flue connection to the chimney is short, direct and consists of as few el- bows as possible. When possible, the unit should be centralized with respect to the supply and return air ductwork. A central location minimizes the trunk duct sizing.
Minimum installation clearances are listed in Table 1.
NOTE: The recommended installation clearances do not necessarily take into consideration the clearances necessary to replace the air filter or perform other routine maintenance.
