1.3 Warranty
NATCO Heating Systems’ appliances are covered
by a limited warranty. Owners should submit online
warranty registration at
www.National Combustion.com .
All warranty claims must be made to an authorized
National Combustion Co. representative or directly to
Customer Service. Claims must include the serial
number and model (this information can be found on the
rating plate), installation date, and name of the installer.
Shipping costs are not included in the warranty
coverage.
Some accessory items are shipped in separate
packages. Verify receipt of all packages listed on the
packing slip. Inspect everything for damage immediately
upon delivery, and advise the carrier of any shortages or
damage. Any such claims should be filed with the
carrier. The carrier, not the shipper, is responsible for
shortages and damage to the shipment whether visible or
concealed.
1.4 Dimensions
See Figures 1 and 2.
1.5 Locating the Appliance
The appliance should be located to provide
clearances on all sides for maintenance and inspection. It
should not be located in an area where leakage of any
connections will result in damage to the area adjacent to
the appliance or to lower floors of the structure.
When such a location is not available, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance.
The appliance is design certified by CSA-
International for installation on combustible flooring; in
basements; in closets, utility rooms or alcoves
. Fire
Coil 85 Boilers or Water Heaters must never be
installed on carpeting.
The location for the appliance
should be chosen with regard to the vent pipe lengths
and external plumbing. The unit shall be installed such
that the gas ignition system components are protected
from water (dripping, spraying, rain, etc.) during
operation and service (circulator replacement, control
replacement, etc.). When vented vertically, the Fire Coil
85 must be located as close as practical to a chimney or
outside wall. If the vent terminal and/or combustion air
terminal terminate through a wall, and there is potential
for snow accumulation in the local area, both terminals
should be installed at an appropriate level above grade.
The dimensions and requirements that are shown in
Table 1 should be met when choosing the locations for
the appliance.
1.6 Locating Pump-Mounted Water Heater
with Respect to Storage Tank(s)
For best results, a pump-mounted Fire Coil 85
water heater should be located within 15 feet (4.6m) of
the storage tank(s). The pump is sized for 30 feet (9.1m)
of piping.
If the appliance must be installed with longer piping
runs, then larger diameter pipe or tubing shall be used.
Consult the factory for assistance.
