Combustion Air Fan
The combus t ion ai r fan regul at es t he fl ow of air i nto t he FFBH t o s upport combus ti on of the fuel suppli ed by t he auxi liaryfuel pump. It i s als o us ed t o purge and cool the FFBH.
Burner Housing
The burner hous ing cont ai ns the burner i nsert and als o i ncorporat es connecti ons for t he exhaus t pipe, the coolant inl etfrom the auxil iary coolant pump and t he cool ant out let t o t he vehi cl e heater.
The burner ins ert i ncorporat es t he fuel combus t ion chamber, an evaporator and a gl ow pin and fl ame s ens or. Fuel from t heauxi li ary fuel pump is s uppl ied t o a vent uri, where it evaporat es and ent ers t he combust ion chamber to mix wit h air fromt he combus ti on air fan. The gl ow pin and fl ame s ens or provides t he igni ti on source for t he fuel:air mi xture and, oncecombus t ion i s es tabli shed, monit ors t he flame.
Heat Exchang er
The heat exchanger t ransfers heat generated by combus ti on t o the coolant . Two s ens ors are i nst all ed in t he heatexchanger cas ing t o provide the control modul e wi th i nput s of Engine Coolant Temperature (ECT). The cont rol module us est he temperat ure inputs t o control s ys tem operati on.
Air Inlet Hose and Muffler
A canis ter t ype muffler i s included in the ai r inlet s upply l ine. The muffler reduces the noi se caus ed by inducti on roar.
Exhaust Pipe and Muffler
The exhaus t pipe and muffl er di rects exhaus t combus ti on gases t o at mos phere below t he front RH wheel arch. Exhaus tvapor may be vi s ible when the FFBH i s running, dependi ng on atmos pheri c condit ions .
Control Module
The cont rol module cont rols and moni tors operati on of the FFBH sys tem. An int ernal flow of ai r from t he combust ion ai r fanvent il ates t he cont rol module to prevent i t overheat ing.

PRINCIPLES OF OPERATION
If a heat ing reques t i s received and t he ambient air t emperature is les s t han or equal to 5°C (41 °F), t he ATC modulet ransmit s a 'supplement al heat' mes s age to the FFBH control modul e over the medi um speed CAN bus . The control modul eres ponds by ret urning a 's uppl ement al heat ' st atus mess age back to the ATC modul e. The control modul e wi ll now i nit iatet he FFBH st art s equence.
If the heati ng reques t is removed, or ambient air t emperat ure ris es t o 8°C (46 °F), the ATC modul e t rans mit s a 'heat er off'mes s age to t he FFBH cont rol module over t he medium s peed CAN bus . Again, t he cont rol module res ponds by returni ng a'heater off' s tat us mes sage back to the ATC modul e. The cont rol module wi ll now de-act ivate the FFBH.
If maxi mum heat ing i s reques ted, Engi ne Cool ant Temperature (ECT) becomes the overriding factor. In t his i nst ance, t heATC module wil l change the CAN bus mes sage from 'heater off' to 's uppl emental heat ' when ECT is bel ow or equal t o 70°C(158°F). If ECT ri ses to 78°C (172°F) t he ATC module returns the mess age t o 'heater off'.
The cont rol module wil l not s t art t he FFBH, or wil l dis cont inue operat ion, if any of the foll owing occur:
The cont rol module is i n t he error l ockout mode (see Diagnostics, below).The engi ne is not runni ng, or s t ops running for approxi mately 4 s econds . The ti me delay i s included for s t alldetecti on.A 'fuel cut -off' mes s age is recei ved from t he CJB over t he medium s peed CAN bus .For addit ional informat ion, refer t o: Air Bag and Safet y Belt Pretens ioner Supplement al Res traint Syst em (SRS)(501-20B Supplement al Res t raint Sys tem, Des cript ion and O perati on).A l ow fuel l evel mes s age is recei ved from t he CJB over t he medium s peed CAN bus (s ee t abl e below).For addit ional informat ion, refer t o: Ins t rument Clus ter (413-01 Inst rument Cl us t er, Des cript ion and Operat ion).
The cont rol module wil l control FFBH operat ion bas ed on t he fol lowi ng levels of fuel i n the tank.

Start Sequence
At t he begi nni ng of a s tart s equence, t he FFBH cont rol module;
energizes t he glow pi n and flame s ens or t o pre heat the combust ion chambers tarts t he combust ion ai r fan at s l ow s peedand energizes t he auxi liary cool ant pump.
Aft er approxi matel y 30 s econds , the control modul e energizes t he auxi li ary fuel pump at t he s tarti ng s equence s peed. Thefuel deli vered by the auxil iary fuel pump evaporates i n t he combus t ion chamber, mi xes wi th air from the combus ti on air fanand is ignit ed by t he glow pi n and fl ame s ensor. The cont rol module t hen progres s ively increases t he s peed of the auxil iaryfuel pump and t he combus t ion ai r fan. Once combus ti on is est ablis hed t he cont rol module swi tches t he glow pi n and fl ames ens or t o the fl ame s ens i ng functi on to monit or combus ti on. From t he begi nni ng of the st art s equence t o s tabl ecombus t ion at full load t akes approxi mately 150 seconds .
Full and Part Load Combustion
W hi le t he FFBH is running, the control modul e cycl es the heat er bet ween ful l l oad combus t ion, part load combus ti on and acont rol i dl e phase of operat ion, depending on the temperat ure of t he cool ant in t he heat exchanger.
The heat out put level at part l oad combus t ion i s 2.8 kW . Thi s ris es to 5 kW at full l oad combus ti on. The control modul et ransmit s t he amount of fuel us ed by t he FFBH to the i nst rument clus t er, and t he FFBH coolant t emperature t o t he ATCmodule.
