1.3 Warranty
Laars Heating Systems appliances are covered by a
limited warranty. Owners should submit online warranty
registration at
www.Laars.com.
All warranty claims must be made to an authorized
Laars Heating Systems representative, directly to
Customer Service, or online at
www.Laars.com. Claims
must include the serial number and model number (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 led 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 oors 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 certied by CSA-
International for installation on combustible ooring;
in basements; in closets, utility rooms or alcoves.
Mighty Therm2 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
Mighty Therm2 must be located as close as practical
to a chimney or outside wall. If the vent terminal and/
