MINIMAX NT LOW NOx HSI ELECTRONIC IGNITION LIGHTING/OPERATION - NATURAL GAS
FOR YOUR SAFETY: READ BEFORE LIGHTING
WARNING
If you do not follow these instructions exactly, a fire or explosion may result causing personal injury, loss of life and property damage.
Do not attempt to light the heater if you suspect a natural gas leak. Lighting the heater can result in a fire or explosion which can cause personal injury, death, and property damage.
A.This heater is equipped with an ignition device which automatically lights the main burners. Do not try to light the burners by hand.
B.BEFORE OPERATING, smell all around the heater area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
-Do not try to light any heater.
-Do not touch any electrical switch; do not use any phone in your building.
-Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
-If you cannot reach your gas supplier, call the Fire Department.
C.Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don't try to repair it. Call a qualified service technician. Forced or attempted repair may result in a fire or explosion.
D.Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of the control system and any gas control which has been under water.
