I believe that this model number is for an air conditioner evaporator coil. This unit is probably directly attached to your furnace. The Model number for the furnace will be located in the compartment where the flames can be seen. It will be on a sticker or plate that contains lots of other information too like BTU/h, Volts etc...
The number you gave me gives me this info:
Cased air conditioning evaporator coil.

either the gas at the outside valve is off, or the gas valve at the furnace may be off, or the switch on top of the gas valve in the furace may be off. if they are all on, then you may not be getting a call for heat from the stat to the furnace control board. check to see if you are getting a 24 volt signal from the stat to the w terminal and common terminal on the furnace board. if you are then check to see if the voltage is arriving as 24 volts to the wires at the gas valve itself . if it is then the gas valve is possibly bad. if it is not then the board is possibly bad.look for loose or broken connections on the low voltage wiring. most unusual that the board does everything else but send power to the gas valve. you need to zero in on the valve i think and start by turning off power and that should restart the sequence of operation and you can observe it step by step . if you are not getting a call for heat then the stat may be bad be sure you are in heat , fan in auto and temp pushed up to max. if no 24 volts is sent to furnace board white and common low voltage board then stat is bad. remove it if you think its faulty and jumper the white and red wires together on the subbase. that duplicates what the stat normally does. if the furnace lights its the stat. having said that i realize the stat has to be sending a heat signal or the other stuff would'nt start. so..... back to the furnace board. check that 24 volts in from stat and 24 out to valve and that will put you on your problem item. good luck
