I arrived at Meiga Development Corp in Balzac to evaluate repairs to a large hanging shop heater. They recently had natural gas service to the shop installed. The gas valve was modified and cracked during that time, it is leaking gas, I have shut off the gas shutoff valve. The gas valve must be replaced it is a major safety problem. The draft inducer motor grinds and shakes the whole unit, it is burned out and vibrating, causing bad combustion and overheating. The air pressure switch is operating normally. Parts have been sourced available in Alberta, for freight. Client has declined to commit to repairs at this point, paying dispatch and diagnostics. Need manager approval before signing for repairs. Can apply diag fee to repair or replace option, before oct 22, 2021.
