The Weishaupt Research andDevelopment Institute was establishedin 1962 with the aim to develop excep-tional products in terms of quality andperformance. This commitment wasmade at a time when the concepts of“energy savings” and “environmentalprotection” were not yet consideredissues of social and political importance.

The Weishaupt company and its pro-ducts are founded on the principles ofquality design and performance.

● Certified to international quality stan-dard ISO 9001

● Listed by ETL (UL795/296) and CGA ● Annual sales in excess of 150,000

burners

Burner Design● Forced draft automatic burner● Cast aluminum, hinged monobloc

design● Burner swings open to the left or right● Stainless steel flame tube capable of

withstanding temperatures up to1450° F

● Precision cam arrangement controlsthe fuel and combustion air

● Single servomotor drives the camarrangement and controls the indivi-dual set point for:– High fire position gas/oil– Air damper closed – Ignition position gas– Ignition position oil (RGL)– Low fire position gas– Low fire position oil (RGL)– Stage 2 oil solenoid (GL)– Low fire position gas/oil (GL)

FuelsFollowing fuels can be burned with theburner models G, GL, RGL● Gas

– Natural gas– Liquid gas (Propane)– Manufactured gas– Special gases on request

e.g. digester / sewer gas

● Oil– No.2 Oil (model GL and RGL)

Oil ViscositiesNo.2 OilMaximum viscosity 3.5 cSt at 100°F

Combination Gas/Oil burners aredesigned so that the operation can beswithed from one fuel to the other, either

automatically or manually without furtheradjustments to the burner. Dual gasburners are available on special request.

Electro-Magnetic ClutchThe coupling between the oil pump andthe motor shaft is automatically discon-nected when operating on gas, protect-ing the oil pump from unnecessary wear.

Gas TrainsWeishaupt Gas and CombinationGas/Oil burners are always suppliedwith two (2) safety shut off valves inboth the pilot and main gas trains.

Burner Version and Capacity RegulationGas models “G”– Low/High/Low version ZD controlled

by a servomotor with a running time of8 seconds

– Modulating version ZMD controlled bya servomotor with a running time of 42 seconds

Combination Gas/Oil models “GL”– Low/High/Low gas/oil version ZD

controlled by a servomotor with a running time of 8 seconds

– Modulating gas, Low/High/Low oil version ZMD controlled by a servo-motor with a running time of 20 seconds

Combination Gas/Oil models “RGL”– Modulating gas/Modulating oil version

ZMD controlled by a servomotor witha running time of 42 seconds

Air/Fuel RegulationLow/High/Low and Modulating gasThe adjustable cam arrangement on theburner results in a simultaneous move-ment of the air damper and gas butterfly.The air quantity can be matched to thegas quantity throughout the firing range.This precise regulation results in an opti-mum fuel/air ratio and improved turndown figures.

Low/High/Low oilThe low fire (stage 1) and high fire(stage 2) oil solenoid valves are con-trolled by micro switch set points on theservomotor, which permit preciseadjustment of fuel and air.

Modulating oilThe adjustable cam arrangement resultsin a simultaneous movement of the airdamper and oil flow regulator. The air

quantity can be matched to the oil quan-tity throughout the firing range andimproved turn down figures.

Controlled shut downThe control system is designed toensure a controlled shut down of theburner at the low fire position. After acontrolled shut down the air damper dri-ves automatically closed.

Ignition positionBurner models “G” and “GL” provide anindependent ignition position, in additionto the low fire position, when operatingon gas.

Burner model “RGL” provides a sepa-rate ignition position and separate lowfire positions for both gas and oil.

This feature permits the burner to betuned to the appliance, allowing only avery small quantity of gas (or oil) to be released for light off.

Flame supervisionStandard methods of flame monitoringare: ● a flame rod for Gas ● a UV scanner for Combination

Gas/Oil

Flame Monitoring SystemsThe burner flame monitor sequencesand controls the operation of the burnerautomatically. The flame monitor can be located in either the burner control panelor mounted directly on the burner. Thestandard flame monitoring system usedis manufactured by Landis & Staefa.

Alternative flame monitoring systems utilizing configurations of the Honeywell7800 series and Fireye E 110 are available upon request.

Site of InstallationThe standard version of Weishaupt burn-ers is designed for operation in enclosedareas with ambient temperatures from15°F to 100°F (-10°C to +40°C)

The capacity graphs are representa-tive of tests performed under condi-tions as stated below.

The minimum firing rate may varyfrom application to application. In cer-tain cases, a greater turn down ratiois possible.

Test Criteria:All figures relate to an ambient tem-perature of 70ºF (20ºC) and a site ele-vation of 1,650 ft (500m) above sealevel.

The capacity graphs are based on fuelwith low calorific value.

Gas burner version LN Using the especially low emission gasburners G1 and G3, version LN, themost stringent regulation and limits ofvarious emission regulating standardscan be achieved.
