What causes low heat output on the grills ?
A. Most commonly asked in relation to propane grills, the pressure sensing device in the regulator is engaged when it senses insufficient back pressure. Its purpose is in the event there is a leak downstream, the gas flow is reduced thereby minimizing danger and alerting the user that there is something wrong with the grill. With natural gas the gas supply piping size may be inadequate for the demand of the grill, extremely windy conditions and finally sear plates that are improperly installed will affect the disbursement of heat and cause hot and cold spots.
