My Rinnai 1004F direct-vent wall furnace is giving me error code 99. it won't light up.? Mfr Manual says of the error code 99: Flue Block Check around the flue terminal for blockage. I checked and there is no blockage. So when I turn it on, air intake goes on for few seconds then it stops with error code 99. Any idea what is wrong?
This fusible link may be open. Try jumpering the two leads and see if the unit operates. If it does replace the fusible link. Do not operate the unit without the fusible link for an extended period. It is a safety device and is there for a reason. Hope this helps.
Testimonial: "Thanks for the info. By the fusible link, did you mean the part F (Fuse) or the thermal fuse (TF) which consists of TF1, TF2 amd TF3?"

A 49 error code is caused by the pressure switch either not proving or a bad component. Check the hose attached from the plastic elbow located behind the heater going to a small square pressure switch found inside the heater. It may have come loose or a mouse may have taken a bite out of it. Also while you are behind the heater, pull off the hose that looks like a vacuum cleaner hose and run the heater with it unattached. If it runs, you have a blockage in the vent. If not, take a flashlight and go outside to the vent. Look down the center pipe for any obstructions. If it still does not work, you may need a new pressure switch.
While the front panel is off the heater, cycle the heater to attempt a start. You want to make sure the blower turns. If it does not, check the wire connections to it. You may be looking at a bad blower. If it is turning but still does not start, we are looking at a bad pressure switch.
Let me know what you find, I may have a switch or blower motor that you can purchase.

gday nelson. if you check out the specs on the rinnai range you will find another one that will go straight in. if you buy new it will come with a new flue kit. as far as recomended installation heights most of them are quite flexible. i installed a second hand 403ft yesterday with the centre of the flue at 140mm from the floor. recomended in the instructions were 240mm. a mate gave me the heater and i just had to buy a flue kit as the old one was already too short. if you messure your flue from inside and send me the specs i can give you a more difinitive answer.

Remove the two screws on the side trim. Remove the two top screws from the filter panel. Reach behind the heater and pull the sock down on the vent pipe. unclip the two clamps holding the vent pipe together. Remove the plastic elbow off of the vent termination. Slide the heater to the left to slide the vent pipe off of the vent termination. Remove the gas line after shutting the gas off.
