Garage Or Utility Room Installation (Vent Installation - Indoor Installation Us And Canada); Final Installation Check - Pentair ETi 250 Installation And User Manual

GARAGE OR UTILITY ROOM INSTALLATION
Risk of fire and explosion if installed at floor level in an automotive garage or near gasoline or flammable liquid storage.
Gasoline fumes are heavier than air and will settle to floor level in closed spaces. Gasoline fumes and spilled gasoline or other
volatile liquids (such as some paints and varnishes) will travel across the floor and can be ignited by a gas appliance.
In any utility room or residential garage installation, install the heater with the base at least 18 inches (.5M) above the
floor, see Figure 31. In a garage, install a rail or wall to protect the heater from physical damage by a moving vehicle.
NOTICE: A Propane fired heater must not be installed in a garage in Massachusetts, by order of the Massachusetts State Fire
Marshal. For more information, call the Massachusetts State Fire Marshal's office.
VENT INSTALLATION –
INDOOR INSTALLATION (U.S. AND CANADA)

FINAL INSTALLATION CHECK

After heater installation, check and verify the following:
• Check that horizontal vent pipe runs slope uniformly at least 1/4" per foot (2 cm per meter) upward from the heater to
the vent terminal. No sags, no dips, no high or low spots.
• Check that vent is supported at elbows, tees, and horizontal and vertical runs according to manufacturer's instructions
and code requirements.
• Check that vent supports and wall and ceiling penetrations allow free movements up, down, and sideways without causing
any strains on the heater or vent body.
• Check for at least six inch (15 cm) free air clearance between the heater vent pipe and combustible materials.
• There should be at least 30 in of clearance in front of the heater to provide adequate service space and access to the
operator control panel, electrical controls and other operating components.
• Check that all joints are completely together and sealed.
• In Florida, building codes require that the heater be anchored to the equipment pad or platform to withstand high wind
pressures created during hurricanes. A hold down bracket kit is designed to hold the unit to the equipment pad in high
wind conditions. Installation of the anchor clamps are recommended in all installations and are required in Florida, (See
Florida Building Code 301.13). For hurricane mounting bolts and clamps, purchase Bolt Down Kit P/N 476004.
WARNING
