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.
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 CSD-1.
C.
Provide clearance between combustible material and
boiler jacket (following clearances are minimums):
1. 16H-340: listed for Alcove installation
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.
2. 16H-410-16H-505: for installation in room which is
large in comparison with size of boiler.
a. Front: 18”
b. Top: 51½”
c. Draft hood, rear, sides, and flue connector: 6”
D.
Provide clearance for servicing and proper operation
(following clearances are recommended and may be
reduced to minimum clearances shown above):
1. Single boiler, 16H-340, Front: 24” (61.0 cm)
2. Single boiler, 16H-410-16H-505, Front: 48”
(122.0 cm)
3. Multiple/modular boiler, 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.
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 [ft
3
] = 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 ft
3
per
1,000 Btuh, space is considered an
unconfined
space
.
b. If result is less than 50 ft
3
per 1,000 Btuh, space
is considered a confined space .
4. Determine building type. A building of unusually
tight construction has the following characteristics:
a. Walls and ceiling exposed to outside atmosphere
have a continuous water vapor retarder with a
