I. Pre-Installation
WARNING
Carefully read all instructions before installing boiler. Failure to follow all instructions in proper order can cause personal injury or death.
A. Inspect shipment carefully for any signs of damage. All equipment is carefully manufactured, inspected and packed. Our responsibility ceases upon delivery of boiler to carrier in good condition. Any claim for damage or shortage in shipment must be filed immediately against carrier by consignee. No claims for variances or shortages will be allowed by Boiler Manufacturer, unless presented within sixty (60) days after receipt of equipment.
B.Installation must conform to the requirements of the authority having jurisdiction. In the absence of such requirements, installation must conform to the National Fuel Gas Code, NFPA 54/ANSI Z223.1 and/or CAN/CSA B149.1 Installation Codes. Where required by the authority having jurisdiction, the installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME No
C.Provide clearance between combustible material and boiler jacket (following clearances are minimums):
1.USA,
a.Front: 18”
b.Top: 36”
c.Draft hood, rear, sides and flue connector: 6”
WARNING
Appliance is design certified for installation on noncombustible flooring only. For installation on combustible flooring only when installed on special base listed in Table 2. Boiler must not be installed on carpeting. When boiler is installed on concrete which is over a material that is subject to melting (PVC, PEX radiant tubing, etc.), the special base must be used. A concrete pad is not sufficient to protect combustible flooring.
Table 2: Special Base Required for Installation on Combustible Flooring
Boiler Model | Special Base Part Number |
805H | 61816055 |
806H | 61816065 |
807H | 61816075 |
808H | 61816085 |
809H | 61816095 |
810H | 61816105 |
2.USA,
a.Front: 18”
b.Top: 51½”
c.Draft hood, rear, sides, and flue connector: 6”
3.Canada,
a.Top and front: 18” (45.7 cm)
b.Flue, rear and sides: 6” (15.2 cm)
D.Provide clearance for servicing and proper operation (following clearances are recommended and may be reduced to minimum clearances shown above):
1.Single boiler,
2.Single boiler,
(122.0 cm)
3.Multiple/modular boiler, USA /Canada, Sides: 1” (2.5 cm)
E.Install boiler on level floor as close to chimney as possible. For basement installation provide a solid base such as concrete or masonry construction if floor is not level or if water may be encountered on floor around boiler.
F.Protect gas ignition system components from water (dripping, spraying, rain, etc.) during boiler operation and service (circulator replacement, control replacement, etc.).
G.Provide combustion and ventilation air in accordance with applicable provisions of local building codes,
or the National Fuel Gas Code, NFPA 54/ANSI Z223.1, Air for Combustion and Ventilation; or CAN/ CSA B149.1, Venting Systems and Air Supply for Appliances.
WARNING
Adequate combustion and ventilation air must be provided to assure proper combustion.
The following guideline is based on the National Fuel Gas Code, NFPA 54/ANSI Z223.1.
1.Determine volume of space (boiler room). Rooms communicating directly with space (through permanent openings not furnished with doors) are considered part of space.
Volume [ft3] = Length [ft] x Width [ft] x Height [ft]
2.Determine Total Input of all appliances in space. Round result to nearest 1,000 Btu per hour (Btuh).
3.Determine type of space. Divide Volume by Total Input.
a.If result is greater than or equal to 50 ft3 per 1,000 BtuH, space is considered an unconfined space.
