Use and Care Manual

• DO NOT vent near soffit vents, crawl space vents, or other areas where condensate or vapor could create a nuisance or hazard or cause

property damage.

• DO NOT vent where condensate vapor could cause damage or could be detrimental to the operation of regulators, relief valve, or other

equipment.

• Maximum Snow Level Determination: These installation instructions reference snow levels in establishing a minimum height for the installation of

exhaust vent or air intake terminations. Snow levels shall be determined as follows:

a. The installation location may, by ordinance, designate how snow levels are calculated in that location; or

b. In the absence of specic ordinances, snow levels shall be calculated from the average monthly maximum depth of snow accumulation as

indicated by the National Weather Service’s 10 year statistics for the installation location/geographical area.

In addition:

• Total length of vent piping shall not exceed the limits specied in this manual.

• The ue products coming from the exhaust vent will create a large plume when the heater is in operation. Avoid venting in areas that will affect

neighboring buildings or be considered objectionable.

• DO NOT locate exhaust vent or intake pipe in a parking area where machinery may damage the pipe.

In the Commonwealth of Massachusetts and as Required by State and Local Codes:

• The vented gas fueled appliance shall not be installed so its combustion, ventilation, or dilution air is obtained from a bedroom or bathroom.

• Signage: Whenever any through-the-wall (horizontal or sidewall) vent is installed less than seven feet above the nished grade, a metal or plastic

identication plate shall be permanently mounted to the exterior of the building at a minimum height of eight feet above grade directly in line with

the exhaust vent terminal. The sign shall read, in print no less than 0.5 inches in size, “GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL

OBSTRUCTIONS".

• Marking of Exhaust Vent and Intake Pipe: Piping used for ventilation, make-up, or combustion air intake shall be labeled as follows:

a. Throughout the entire developed length:

i. Labels must be placed every ten feet for exposed/visible piping; or

ii. Labels must be placed every three feet for concealed piping.

b. At all changes of direction;

c. On each side of a penetration through a partition, wall or ceiling; and

d. The labels shall be black lettering that:

i. Indicates that the piping is used for ventilation, make-up, or combustion air intake, and

ii. The letters shall be sized equal to a minimum of the pipe diameter. However, for piping with a diameter exceeding two inches, said lettering

does not need to be larger than two inches.

WARNING

The building owner is responsible for keeping the exhaust and intake terminations free of snow, ice, or other potential blockages, as well as

scheduling routine maintenance. Failure to keep the vent piping terminations clear and properly maintain the heater could result in property

damage, severe personal injury, or death.

For each oor containing bedroom(s), a carbon monoxide detector and alarm shall be placed in the living area outside the bedrooms, as well as

in the room that houses the heater. Detectors and alarms shall comply with NFPA 720 (latest edition). Failure to comply with these requirements

could result in product damage, severe personal injury, or death.
