Re: heater

On the blower, look for a Blue wire, Red wire and maybe an Orange wire. The Red wire is low spped, Orange is Med-Low and Blue is Medium. Look on the circuit board and see what colors are on "Park" and what color is on "Load" or "Line". Swap that wire to what ever speed you want. Remember that increased speed will make the air from the registers a little cooler.

When heater is turned on high it will not stay on

It sounds like the thermostat, but check to make sure that there is nothing blocking air flow through the heater. If it was damaged, there could be loose parts inside blocking air flow.

Incomplete combustion --excess smoking-

These heaters are tempermental there are several things that can cause this. Lets start with the easiest and go from there, 1- if this heater sat with fuel in it for the off season it could be contaminated fuel (water) condensation builds up from temperature changes,solution change fuel. Most heaters have an inline fuel filter, look at it even go so far as to use air pressure to blow air backwards thru the filter this will clear blockages and let you know whether it is time to replace the filter. Insufficient fuel flow can cause this as well so remove the top cover and attenpt to start the heater watch for a fine mist from the nozzle it may be time for a new nozzle, please pay attention to nozzle size and GPH ratings.

Furnace runs for about 1-2 min to heat when time for fan stage.. shuts down

the fan may need replacing it may be faulty, but on the ither hand how long since furnace serviced it may be over temping before fan kicks in which means needs the air flow looking at! air flow on a majority of heaters is important if you don't have enough the heater will high temp and shut down, but it sounds if it may be the fan itself if the heaters turning off before fan starts it could be because of a faulty sensor or fan motor ceased and not spinning causing it to trip so firstly look at fan and see if you can see why its faulting if it is also i would check your airflow makes sure that clean enough to get good air flow and if ducted heating check the return air to unit and if has filter take out and try running there could be a lot of reasons for this but usually its air flow or fan if you are not electrically minded i would seek a qualified repair agent for furnace

165 heater is making alot of smoke

Smoke is an indication of an improper air/fuel mixture, partially blocked nozzle or blocked air passages.

Kerosene must be atomized and mixed with the right amount of air to burn without smoke and odor.
You should consult your manual to have a guide to resolving the issue.
1. Make sure pump pressure is set accurate (5.6 p.s.i.). The pump controls the air/fuel mixture.
2. remove nozzle and clean with brush and compressed air. Also inspect rear of combustion chamber where air flows into and around the chamber to ensure proper air flow. Any materials that may be bent should be replaced. If not formed properly, the air flow through the heater changes as a result.

Yes, look at the control board and follow a larger diameter red wire and see if it goes to the blower. Now follow the orange wire from the blower to the circuit board and swap wire locations with the red one. This will change the blower speed from Low to Medium Low. The Blue wire will give you Medium and may be too fast. The faster the blower goes, the cooler the air feels coming out of the registers. If your ductwork is undersized or your air filter is too restrictive, this will interfere with air flow and not deliver the necessary heat when you need it. Changing the blower speed is only a band-aid to bigger issues.

I hope this helps!

Low air flow

most fan forced wall heaters do not move a lot of air. check the cfm rating on the heater. the fan sucks in air from the bottom and forces it up to the top where the element is. broan and nutone have good air flow.
