SPECIFIC SAFETY RULES AND PRECAUTIONS
1.U.S.....No. 1 or No. 2 heating oil only (ASTM D396),
CANADA.....No. 1 stove oil or No. 2 furnace oil only are approved for use and can be burned in this furnace. Refer to the furnace rat- ing plate or SECTION IV of these instructions.
2.Install this furnace only in a location and position as specified in SECTION I of these instructions.
3.An
4.Combustion products must be discharged outdoors. The Roof Jack vent system is the only approved vent system that can be installed on this furnace. Install as specified in SECTION VI of these instructions.
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly could result in serious injury, death or property damage.
Read all instructions before proceeding. Follow all instructions com- pletely. Failure to follow these instructions could result in equipment malfunction, causing severe personal injury, death, or substantial property damage.
5.Test for leaks in the oil line as specified in SECTION VIII of these instructions.
6.Always install the furnace to operate within the furnace’s intended temperature rise range. Only connect the furnace to a duct system which has an external static pressure within the allowable range, as specified on the furnace rating plate.
7.The return air duct system is not required by the furnace manufac- turer. This furnace utilizes a sealed combustion air and vent sys- tem referred to as a roof jack. The Roof Jack must be installed as specified in these instructions and must conform with state, local, or regional codes.
8.It is permitted to use the furnace for heating of buildings or struc- tures under construction. Installation must comply with all manu- facturer’s installation instructions including:
•Proper vent installation;
•Furnace operating under thermostatic control;
•Return air filter door must be sealed to the furnace;
•Air filters in place;
•Set furnace input rate and temperature rise per rating plate marking;
•Means for providing outdoor air required for combustion;
•Return air temperature maintained between 55ºF (13ºC) and 80ºF (27ºC);
•The air filter must be replaced or thoroughly cleaned upon sub- stantial completion of the construction process;
•Clean furnace, duct work and components upon substantial completion of the construction process, and verify furnace operating conditions including ignition, input rate, temperature rise and venting, according to the manufacturer’s instructions.
The following requirements to be met:
a.Clean, outside combustion air is provided to the furnace to minimize the impact of corrosive adhesives, sealants, and other construction materials. Drywall dust is a major concern during construction, which can be pulled into the combustion air path, leading to plugged heat exchangers, burners, and inducer assemblies.
b.Filter must be installed in the furnace as specified in the installation instructions, and must be replaced or thoroughly cleaned prior to occupancy of the home. Again, drywall dust is the key issue, as that dust can be pulled into the circulating blower motor, plugging the motor vents, coating the rotors and stators, etc. which can lead to a potential fire hazard.
c.The temperature of the return air to the furnace must not be less than 55° F (13° C), with no evening setback or furnace shutdown, to prevent condensation in the primary heat exchangers.
d.The air temperature rise must be within the stated rise range as indicated on the furnace rating plate, and the firing input rate must be set to the unit nameplate value.
e.The external static pressure of the air distribution system ductwork must be set for heating operation to be at least 0.12 (.03 kPA) to 0.30 (0.7 kPA) inches water column, based on the input rate of the furnace, with the lower value for input rates at 66,000 btu/hr and the upper value for units with input rates at 84,000 btu/hr.
f.The furnace and ductwork should be thoroughly and com- pletely cleaned prior to occupancy of the dwelling to insure the proper operation of the furnace and to avoid potential health concerns.
9.In Canada refer to the
10.The size of the unit should be based on an acceptable heat loss calculation for the structure. ACCA, Manual J or other approved methods may be used.
11.Manufactured (Mobile) Home and Modular Home Installation: This appliance must be installed in a (sealed combustion) configu- ration using a roof jack vent system. A roof jack is the only approved vent system that can be used to vent this appliance.
12.Modular Home Definition:
13.Manufactured (Mobile) Home Definition:
14.This furnace is approved for installation in trailers or recreational vehicles.
SAFETY REQUIREMENTS
•Never attempt to alter or modify this furnace or any of its com- ponents.
•Never attempt to repair damaged or inoperable components. Such action could cause unsafe operation, explosion, fire and/ or asphyxiation.
•If a malfunction has occurred, or if you feel that the furnace is not operating as it should, contact a qualified service agency or oil supplier for assistance.
•A manufactured (mobile) home installation must conform with the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280, Federal Manufactured Home Construction & Safety Standard (H.U.D., Title 24, Part 3280) or when such stan- dard is not applicable, the standard for Manufactured Home Installations (Manufactured Home Sites, Communities, and Set- ups) NFPA 31 Installation of
•Refer to the unit rating plate for the furnace model number, and then see the dimensions page of these instructions for return air door dimensions in Figure 2. The filter(s) must be installed according to the instructions.
