Techniciens—Veuillez vous conformer à la réglementation en viguer concernant 1’ installations des détecteurs d’oxyde de carbone. Suivre les
consignes d’entretien figurant dans le manuel d’instruction ci-joint.

Boiler Sizing

1. Check to be sure you have selected the BW9 boiler with the proper capacity before starting the installation. The I=B=R Rating of the boiler

selected should be greater than or equal to the calculated peak heating load (heat loss) for the building or area(s) served by the boiler and
associated hot water heating systems. See boiler rating and capacity table on page 5 of this manual.

2. Heat loss calculations should be based on approved industry methods.

Considerations for Boiler Locations

Before selecting a location for the boiler, the following should be considered. Each boiler considered for installation must be:

1. Supplied with the correct type of gas (natural or propane).

2. Connected to a suitable combustion air intake piping system to supply the correct amounts of fresh (outdoor) air for combustion. (Maximum

length 80 ft for BW9-100 boiler, and Maximum length 100 ft for BW9-75 and BW9-50 boilers).

3. Connect to a suitable venting system to remove the hazardous products of gas combustion (Maximum length 80 ft for BW9-100 boiler, and

Maximum length 100 ft for BW9-75 and BW9-50 boilers).

4. Connected to a suitable hot water heating system.

5. Supplied with a suitable electrical supply for all motors and controls.

6. Connected to a properly located thermostat or operating control (not included with boiler).

7. Placed on level surface (must NOT be installed on carpeting).

8. Condensate drain line must be pitched down to floor drain or external condensate pump with reservoir at 1/4-in. per foot (wood frame or

blocks may be used to raise boiler).

Locating the Boiler

1. Select a location which is level, central to the piping systems served and as close to the vent and air intake terminals as possible.

2. Accessibility clearances, if more stringent (i.e. larger clearances) than required fire protection clearances, must be used for the boiler

installation. Accessibility clearances may be achieved with the use of removable walls or partitions.

3. The boiler is approved for installation in closets and on combustible floors. This boiler shall NOT be installed on carpeting.

4. The clearances shown in Table 4 indicate required clearances per AGA and CGA listing. A minimum 1-in. clearance must be maintained

between combustible construction and each of the left, right, top, and back surfaces of the boiler. A minimum 8-in. clearance is required
on the right side, to allow room for the inlet air pipe. An 18-in. clearance must be maintained at a side where passage is required to access
another side for cleaning or servicing, inspection or replacement of any parts that normally may require such attention. Allow at least 24-in.
at the front and left side and 8-in. at the top for servicing. No clearances are required to venting or combustion air intake piping.

5. Equipment shall be installed in a location which facilitates the operation of venting and combustion air intake piping systems as described

in this manual.

6. Advise owner of boiler to keep venting and combustion air intake passages free of obstructions. Both the venting and combustion air intake

piping systems connected to the outdoors must permit flow through the piping systems without restrictions for the boiler to operate.

7. The boiler shall be installed such that the automatic gas ignition system components are protected from water (dripping, spraying, rain, etc.)

during operation and service (circulator replacement, control replacement, etc.).
