GENERAL INFORMATION
2
Clearance must be in accordance with the local installation codes and the requirements of the gas supplier.
Never operate the heater unless it is vented to the outdoors and has adequate air supply to avoid risks of
improper operation, fire, explosion or asphyxiation.
DO NOT install this boiler directly on a carpeted floor. A fire hazard may result. The boiler shall be
installed on a metal or wood panel extending beyond the full width and depth of the boiler by at least 3
inches (76.2mm) in any direction or, if the boiler is installed in an alcove or closet, the entire floor shall be
covered by the panel.
For safe operation, an ample supply of air must be provided for proper combustion and ventilation in
accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54 National Fuel Gas Code CSA/B149.1
Natural Gas and Propane Installation Codes or applicable provisions of the local building codes. An
insufficient supply of air may result in a yellow, luminous burner flame, carboning or sooting of the heat
exchanger, or create a risk of asphyxiation. Do not obstruct the flow of combustion and ventilation air.
This unit is not intended to operate at gas supply pressures other than those shown on the rating plate. Exposure
to higher gas supply pressure may cause damage to gas valves, which can result in fire or explosion. If over-
pressure has occurred, such as through improper testing of gas lines or emergency malfunction of the supply
system, the gas valves must be checked for safe operation.
A thermostatic mixing valve must be added to this system to prevent scalding, if regulated by local
codes and authorities.
Check the Rating Plate
PENSOTTI units come from the factory configured for use with either LP or Natural Gas. Prior to installation,
check the rating plate of the boiler to ensure the unit matches gas type, gas pressure, water pressure and
electrical supply. If the unit does not match the requirements, do not install.
Be sure the gas type and electricity voltage match the rating plate.
There is a risk in using fuel burning appliances in rooms or areas where gasoline, other flammable liquids or
engine-driven equipment or vehicles are stored, operated or are repaired. Flammable vapors are heavy and
travel along the floor and may be ignited by the igniter or main burner flames causing fire or explosion. Some
local codes permit operation of gas appliances if installed 18 inches or more above the floor. This may reduce
the risk if location in such an area cannot be avoided. Flammable items, pressurized containers or any other
potential fire hazardous articles must never be placed on or adjacent to the boiler. Open containers of
flammable materials should not be stored or used in the same room with the boiler.
Do not install the PENSOTTI boiler in areas with excessive high humidity.
Do not install the unit in location where there is excessive humidity, such as a bathroom, damp crawl space, and
other areas with high levels of humidity. This may cause the unit to malfunction.
To avoid possible electrical shock, DO NOT touch the internal components of the boiler or the power cord with
wet hands
.
DO NOT splash excessive water on the boiler when cleaning, as they are water resistant, not water proof.
Professionally qualified personnel in accordance with current laws and standards and in line with the
manufacturer
’s instructions must install the appliance.
The commissioning of the boiler and any subsequent work carried out on the appliance must be effected by an
appropriately qualified technician.
The appliance must be used solely for the purpose for which it has been designed and manufactured: central
heating and domestic hot water production. Any other use is deemed as improper and as such dangerous.
Under no circumstances will the manufacturer be held responsible for damage or injury to persons or animals
caused by errors in the installation and/or use of the appliance, or through non-compliance with current local and
national standards and/or the manufacturer
’s instructions.
The installation, operation and maintenance manual and forms are an integral and essential part of the product
and must be kept with the appliance always.
The warnings contained in this chapter have been written for the appliance user, the installer and the service
technician.
