CHECK CERTIFICATIONS / APPROVALS

•Underwriters Laboratories has certified this burner to comply with ANSI/UL 296 and has listed it for use with #1 or #2 fuel oil as specified in ASTM D396. Low sulfur #1 and #2 fuel oils reduce heat exchanger deposits with all burners compared to the stan- dard fuels. Reduced deposits may extend the service interval for cleaning and improve the efficiency of the appliance over time. Low sulfur fuels reduce particulate and oxides of nitrogen emis- sions as well. The Oil Heat Manufacturers’ Association recom- mends these fuels as the preferred fuels for this burner.

•State and local approvals are shown on burner rating label (See Figure 1).

•All oil burners must be installed in accordance with the regula- tions of the latest revision of the National Fire Protection Associa- tion Standard NFPA 31 and in complete accordance with all local codes and authorities having jurisdiction. Regulation of these authorities take precedence over the general instructions pro- vided in this installation manual.

FURNACE LOCATION AND CLEARANCES

The furnace shall be located using the following guidelines:

1.The furnace should be located where the roof jack can be installed without major modifications to the roof of the structure.

2.As centralized with the air distribution as possible.

3.Where there is access to fresh air particularly when the blend air accessory will be installed.

4.Where it will not interfere with proper air circulation in the confined space.

5.Where the outdoor section of the roof jack will not be blocked or restricted. Refer to “VENT CLEARANCES” located in SECTION VI of these instructions. These minimum clearances must be main- tained throughout the installation.

6.Where the unit will be installed in a level position with no more than 1/4” (0.64 cm) slope side-to-side and front-to-back to provide a proper roof jack connection and seal.

Installation in freezing temperatures:

1.Furnace shall be installed in an area where ventilation facilities provide for safe limits of ambient temperature under normal oper- ating conditions. Ambient temperatures below 32º F (0º C) may result in the vent temperature falling below 260º F (127º C) at any point in the vent pipe. Vent temperatures below 260º F (127º C) will cause the flue products in the vent pipe to condense causing the vent pipe to deteriorate rapidly.

TABLE 1: Unit Clearances to Combustibles

2.Do not allow return air temperature to be below 55º F (13° C) for extended periods. To do so may cause condensation to occur in the main heat exchanger, leading to premature heat exchanger failure.

Installation in an ambient below 32ºF (0.0° C) could create a haz- ard, resulting in damage, injury or death.

3.If this furnace is installed in an unconditioned space and an extended power failure occurs, there will be potential damage to the internal components. Following a power failure situation, do not operate the unit until inspection and repairs are performed.

Clearances for access:

Ample clearances should be provided to permit easy access to the unit. The following minimum clearances are recommended:

1.Twenty-four (24) inches (61 cm) between the front of the furnace and an adjacent wall or another appliance, when access is required for servicing and cleaning.

2.Twenty-four (24) inches (61 cm) at the side where access is required for passage to the front when servicing or for inspection or replacement of flue/vent connections.

In all cases, accessibility clearances shall take precedence over clear- ances for combustible materials where accessibility clearances are greater.

Check the rating plate and power supply to be sure that the electri- cal characteristics match. All models use nominal 115 VAC, 1 Phase 60Hz power supply.

Furnace shall be installed so the electrical components are pro- tected from water.

Installation in a residential garage:

1.An oil-fired furnace for installation in a residential garage must be installed so the burner(s) and the ignition source are located not less than 18 inches (46 cm) above the floor, and the furnace must be located or protected to avoid physical damage by vehicles.
