If you remove the upper front panel and find the rating plate with model number etc., you will notice a term "temperature rise". Most high efficient furnaces have a temperature rise around 40-70F. That means your return air temp.+
the heat rise thru the furnace (40-70F)= air temp. exiting furnace around 110-140F. Your Pulse furnace should never reach 200F (limit setting).
If the furnace reaches 200F it would shut-off the power to the gas valve, blower would keep running until it cooled down 20-30 degrees below 200F. and then renenergize the gas valve (if the thermostat was still calling for heat).
If you have not, I strongly urge you Omar to have this furnace checked out under the guidelines spelled out by Lennox. (as stated in my earlier
message.) Honest you will be doing yourself and your loved ones a favor.
