MINOR MAINTENANCE EVERY SIX MONTHS
This can be performed by the dwelling occupant.
It is recommended to turn off the cold water isolation valve to the water heater prior to performing general
maintenance. This will prevent the water heater from being used while you clean or spray around the water
heater. Turn on the cold water isolation valve when finished performing the general maintenance.
The minor maintenance includes:

Inspect around the air inlet, flue terminal and the water heater in general for plant growth.
Trim back any shrubs, bushes or other plants which have encroached around the water heater.

Plant growth across the air inlet and flue terminal can interfere with the performance of the water
heater.

Inspect around the water heater for insect infestations, such as ants.
Spray insecticide around the water heater if necessary to rid the area of insects. Do not spray the

surface or into the air inlet or flue terminal of the water heater.
Insects encroaching into or nesting in the water heater can interfere with the operation of the water
heater and also damage components.
Warning: Do not spray the water heater with insecticide while the water heater is running.
Propellants in insect spray may contain hydrocarbon which can catch fire.
