REQUIRED
The following pieces of test equipment will be required to
troubleshoot this system with minimal time and effort.
• Digital M
Multimeter - for measuring AC and DC voltage and
resistance.
• Low PPressure G
Gauge - for checking inlet and manifold
pressures at the gas control valve against dataplate
rating.
■
Visually inspect equipment for apparent damage.
■
Check all hoses for abrasion and wear. Replace any
that are suspect.
■
Make sure heater is properly installed and meets
minimum clearances to nearest combustible
materials. (Refer to dataplate on heater.)
■
Check all wiring for loose connections and worn
insulation.
To effectively use these flow charts, you must first identify
the problem. The problems are numbered sequentially,
along with a brief explanation of each problem. Start at the
diamond closest to the identified problem and proceed with
each step, performing whatever tests are suggested. After
each step or test, the guide will direct the service person to
the next logical step based on the outcome of the previous
check.
Components should be replaced only after each step has
been completed and replacement is suggested in the flow
chart.
The problems are listed below along with the page number
on which you may find the flow chart for the specific
problem.
