Rheem digital gas pool heater fan code


The Fan code would indicate a problem with the combustion air blower. The is a pressure switch to indicate there is sufficent combustion air, and if not then unit shuts down. Either the fan isn't running, or there is an obsturction in the fan or exhaust piping, preventing enough air flow.
cfh would be call for heat, which would be a normal display when water temp is below setpoint
See the link below for a manual. Once you open the page look on lower right side for documents, then install manual

5 year old Laars 25,000 LX won't ignite.


The low pressure indicator is for the gas pressure not the water pressure. The heater won't ignite because it's not getting gas to the igniter. Check gas supply, if okay, check gas connections, valves, etc.

The 1 HP motor should be fine on the jacuzzi.

Reddy kerosine space heater


bucklehead...I assume you discarded the 2 year old fuel... if not do so. Your fuel delivery problem could be caused by a number of things. 1. Incorrect air pump pressure, 2. worn or restricted nozzle, 3. deteriorated fuel line or air line, which in turn is creating the ignition problem, 4. the spark plug is bad OR you may not have a fuel delivery problem at all - just a photocell that has gone bad or has a wasp nest built betweem the eye and the flame (check this first). If the photocell can't see the flame it will shut the heater down. That's it's only job.
