Good morning All
Just finished rebuilding the hot section of my 15 year old 422.
Other than the usual gaskets and burner mat, I chose to replace the combustion ring assy. It was not the least bit deformed, but a spot weld on one of the three legs broke while I was cleaning it. I'll re-weld all three legs and use it as a backup. I even went so far as to weigh both the old and new rings in order to determine if there was any loss in mass due to 15 years of use. Total weight loss was roughly four grams or 3% compared to the new ring. I also cleaned out all of the intake/exhaust paths as well. Only light carbon and soot. Should be good to go for ten more Alaskan years.
During the past 15 years, I've owned both a Monitor 441 and a 422, Two Toyostove 30's, a 73 and an OM 22. I've been asked which brand is more dependable and I must say, I've seen no significant differences. Keep in mind these heaters are electro/mechanical, designed and built by humans. End result is there will be problems with them. Thankfully very few. The vast majority of owners never have problems with their heaters and we never hear from them on the internet. Those of us with issues (heater or other) know where to turn for help. Remember, the key to a long and healthy life of ether a Toyostove or Monitor is preventive maintenance.
Five years ago I left the monitor brand in favor of the Toyostove. Not because I disliked the monitor, but because it was tough to find any service information on the Monitor brand. Not so for the Toyostove. Times have changed and now information is available for both. The quote for the 422 rebuild was $500. It cost me $135 in parts and one day of labor. The pdf. file linked below, was very nice to have as reference and was not easily available to the general public just a couple years ago. I took the exploded view/parts list with me when I went to the dealer to pick up my rebuild parts. His first question to me was "where did you get that list from"?
My reason for putting together this small bit of information and sharing it with others is because I have rebuilt both brands of heaters and now and feel the need to pass along the limited knowledge that I've gleaned when comparing and working on the two. If you have any questions, please don't hesitate to email me.
On a personal note and only my opinion, the comments made by Al Luce over the years at alsheating.com are vindictive in nature and should be taken as such. If he realy wanted to make a difference and help you and I, he would have posted the service manual for the Monitor years ago. Instead, he has chosen to bad mouth a product and the people who service them, leaving us to our own demise seems to be more his stye. My hope is to give a more balanced though limited perspective on the heaters.
My thanks to all who have contributed to this site as well as others.
