I. General Installation Requirements
1INSPECT SHIPMENT carefully for any signs of damage. All equipment is carefully manufactured, inspected and packed. Our responsibility ceases upon delivery of Boiler to the carrier in good condition. Any claims for damage or shortage in shipment must be filed immediately against the carrier by the consignee. No claims for variances or shortages will be allowed by Boiler Manufacturer, unless presented within sixty (60) days after receipt of equipment.
2BOILER INSTALLATION must conform to the requirements of the authority having jurisdiction, or in absence of such requirements to:
a.“National Fuel Gas Code, ANSI Z223.1 obtainable from the American Gas Association, 1515 Wilson
Blvd. Arlington (Rosslyn), VA 22209.
b.When required by the authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired boilers, No.
c.The boiler must be electrically grounded in accordance with requirements of the authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA No. 70.
3THESE GAS BOILERS ARE DESIGN CERTIFIED FOR INSTALLATION on an exterior wall of buildings constructed with combustible materials (wood framed walls with, paneling, drywall, plaster, etc.) or masonry walls (brick, stone, stucco, or cinder block).
4DO NOT INSTALL ON CARPETING. These gas boilers may be installed above carpeted areas. Note: Protect carpeting or flooring to avoid possible damage during installation and maintenance procedures.
5BOILER LOCATION MUST MEET THE FOLLOWING SITE REQUIREMENTS:
a.The boiler must be mounted on a flat wall,
sufficiently strong enough to carry the weight of the unit. (See Figure 1). Minimum acceptable wall construction would consist of 2” x 4” studding on 24” centers. Unit is designed for installation on 16” centers. Therefore, adequate supports must be added between existing studding.
b.A suggested mounting height, where practical, is five feet - six inches from floor to center line of intake air duct opening. (See Figure 1).
NOTE: depending on ceiling height, 6” combustible clearance height from jacket top panel to ceiling must be maintained. (See Figure 3).
c.Consider location of heating supply and return lines, gas supply line, cold water piping and expansion tank in selecting boiler location.
d.Exterior wall surface must be flat to ensure that wall flange can be mounted without being distorted and also provide a positive
If exterior wall surface is not flat (i.e., uneven masonry, stucco, aluminum siding, etc.) a flat surface must be provided of equal size or larger than the exterior wall flange and vent terminal cover.
e.Locate the vent terminal in relation to adjacent public walkways, adjacent buildings, operable windows and buildings, consistent with the National Fuel Gas Code Z223.1: Minimum clearance of
4 feet horizontally from and in no case above or below (unless four [4] foot horizontal distance is maintained), electric meters, gas meters, regulators and relay equipment. At least 12” from any door, window or other building opening. A minimum of 12” above grade, 7” from any overhang, 18” from any side obstruction or wall and 3’ away from any adjacent building. Increase minimum height above grade to maintain adequate clearance above average snow fall for geographical area in which unit is installed. If the unit is to be vented over a public walkway, it must be at least 7” above grade. If the vent terminal is to be within 10’ of a building fresh air intake, it must be at least 3’ above the opening. In addition, avoid venting the unit in corners, niches or areas which might have reduced fresh air circulation. (See Figure 2).

f.If boiler is to be installed above the level of the radiation, a low water cutoff must be installed.
