3.4.2 Liquefied Propane Gas Service
Guspro standard gas burners will operate on Liquefied Propane Gas (LPG). The propane
supply should be determined in consultation with the local propane supplier.
The total BTU requirements for the unit are available on the oven specification plate.
The individual burner ratings are listed on the burner plates.
The natural gas burners supplied as standard equipment can be modified to work with
LPG by changing the orifice size on each burner head. The purchaser may perform at the factory
or in the field this orifice change.
Note: If the orifices on the burners are changed in the field, the oven main line and pilot
regulators may need adjusting. Guspro should be contacted before the change is made.
3.4.3 Oil Service
Guspro Ovens may also be operated with diesel, #1 fuel oil or #2 fuel oil. When oil
burners are supplied, the purchaser must supply an oil supply tank, with supply and return lines
and proper oil filtration.
Note:
• Local oil suppliers should be contacted regarding tank sizing, placement and line
protection in cold weather. Burner sizing and approximate oil requirements are
available from Guspro Inc.
3.5 Water Supply
A galvanized, copper or other rust resistant pipe should supply water supply to the oven.
Clean city water is normally acceptable. Effluents from other plant processes should NOT be
used.
The water mist nozzles on the OTS spray system have orifices that may get plugged by
debris in the water supply. Hard water may also cause spray nozzles to be clogged due to
mineral deposits. It may be necessary to use a water softener with the water supply if the local
water is very hard.
The water pipe should be protected against freezing including suitable valves to drain
water from any exposed pipes when freezing is expected. Provisions for insulation and heat
tracing of water pipes should be made if the oven will be exposed to below freezing conditions.
