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
National
Fuel Gas Code
, ANSI Z223.1/NFPA 54. 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 CSD-1.
C.
Appliance is design certified
for installation on
combustible flooring
. The boiler must not be installed
on carpeting.
D.
Provide clearance between boiler jacket and
combustible material
in accordance with local fire
ordinance. Refer to Figure 1 for minimum clearance
from combustible material for alcove installation.
Provide 1/2" clearance from water piping to
combustible materials.
E.
Provide practical service clearances.
A minimum
of 24" from the right side and front jacket panels is
recommended for servicing but may be reduced to
minimums shown in Figure 1.
F.
Install on level floor.
For basement installation provide
concrete base if floor is not level or if water may be
encountered on floor around boiler.
G.
Protect gas ignition system components
from
water (dripping, spraying, rain, etc.) during boiler
operation and service (circulator replacement, control
replacement, etc.).
H.
Provide combustion and ventilation air
in accordance
with the section "Air for Combustion and Ventilation,"
of the
National Fuel Gas Code
, ANSI Z223.1/NFPA 54,
or applicable provisions of local building codes.
WARNING
Adequate combustion and ventilation air must be
provided to assure proper combustion.
The following guideline is based on the
National Fuel
Gas Code
, ANSI Z223.1/NFPA 54.
1. Determine volume of space (boiler room). Rooms
communicating directly with space (through
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
.
b. If result is less than 50 ft³ 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
rating of 1 perm or less with openings gasketed
and sealed, and;
b. Weather-stripping has been added on openable
windows and doors, and;
c. Caulking or sealants applied in joints around
window and door frames, between sole
plates and floors, between wall-ceiling joints,
between wall panels, at plumbing and electrical
penetrations, and at other openings.
5. For boiler located in an
unconfined space in a
building of
other than unusually tight construction
,
adequate combustion and ventilation air is normally
provided by fresh air infiltration through cracks
around windows and doors.
6. For boiler located within
unconfined space in
building of unusually tight construction
or within
confined space
, provide outdoor air through two
permanent openings which communicate directly or
by duct with the outdoors or spaces (crawl or attic)
freely communicating with the outdoors. Locate one
opening within 12 inches of top of space. Locate
remaining opening within 12 inches of bottom of
space. Minimum dimension of air opening is 3
inches. Size each opening per following:
