8.3 Short Cycling — Boiler

Because the Brute Deluxe is a stage-fired boiler, and its input will decrease when there is a reduction in heating load, short cycling is greatly reduced. If the heating load drops below the minimum input of the boiler for an extended period, the boiler will have a tendency to short cycle. This can be a symptom of improper control strategy or setpoints, or a load distribution problem. Contact your representative to discuss possible remedies.

SECTION 9.

Replacement Parts

Only genuine replacement parts should be used.

9.1 General Information

To order or purchase parts for the Brute Deluxe, contact your nearest dealer or distributor. If they cannot supply you with what you need, contact Customer Service (see back cover for information).

8.4 Short Cycling — Water Heater

9.2 Parts List - see next page.

Short cycling will generally occur only in combination space heating and water heating applications when the water heater is operating in the space-heating mode. Because the Brute Deluxe is a stage-fired water heater and its input will reduce when there is a reduction in heating load, short cycling is greatly reduced. If the heating load drops below the minimum input of the water heater for an extended period, the water heater will have a tendency to short cycle. If short cycling is frequently experienced, regardless of the control’s attempt to limit it, the heating load should be redistributed to control it.

If short cycling occurs in a water heater application, it is probably caused by undersized piping between the water heater and the storage tank or by some other factor that restricts proper water flow through the water heater. The cause should be determined and corrected.

8.5 High Gas Consumption

Appliances operating with an improper air/fuel ratio are very inefficient and consequently, have very high gas consumption. Because efficiency is high when the CO2 is high (or O2 is low), appliances operating with low CO2 or high O2 (especially LP appliances) consume more gas. Adjust the CO2 or O2 for optimum efficiency. If no combustion analyzing equipment (CO2 or O2) is available then a proper adjustment of the air/fuel ratio (CO2 or O2) cannot be accomplished. However, by briefly sniffing the flue gases it is possible to determine if the CO2 or O2 is within the proper range. No significant flue gas odor should be detected when combustion is proper. A strong piercing smell indicates poor combustion and generally a lean mixture - low CO2 or high O2 . The CO2 should be 8% at high fire. To check the CO2, first verify that the supply gas pressure is within 5" to 13" w.c. (1.2 to 3.2 kPa) With the Brute Deluxe running with all stages firing, set the air box pressure to 1.5" w.c. (0.37 kPa) (as a starting point), by adjusting the air shutter(s) at the bottom of the fan(s). Check the CO2, and adjust the air shutters if further adjustment to the CO2 is needed. Sizes 1250 to 2000 have two blowers and two air chambers (boxes). The pressure of each air box must be equal when the final adjustment is made.
