Heatilator told me that i need the GFK4B model. This one does not say B. Do you have the B?

Hi Mike, great question. Our GFK4 is essentially the same thing as the GFK4A or GFK4B. The "A" stood for automatic, which meant the kit included a thermostat. The "B" was used by some brands to indicate that a timer feature was added to the kit, but most manufacturers use "A" and "B" synonymously to mean that the blower kit is automatic. Our GFK4 covers all examples, so if Heatilator recommended the GFK4B, our GFK4 will work wonderfully. If you have any additional questions, just let us know.

i have a lopi berkshire gas stove. i would like to install a fan. will this unit gfk4 fit in my stove? how many sones??? thank you

Bob, if you have 3.5 inches of clearance between the bottom of the lower opening and the top of that same opening you should be able to get this in. You will have to remove anything that is in the bottom of the stove except the gas valve itself. That means the electrial unit that is there and the gas line that feeds the burner unit. Not too bad if you are comfortable with doing it, but if you are uncomfortable with removing gas lines, etc. someone else should do this for you. It takes about 45 minutes from start to finish.

Is this correct for the Heatilator nb4842 model?

Yes, the GFK4 is the correct blower kit for the NB4842 model! Regards, Jason

Will the fit the Desa International fireplace v42ps-a??

Yes, this will fit the V42, but we typically use the larger BKT blower kit on these models. I do have the BKT blower kit available here on Amazon, so let me know if you have any questions. Regards, Jason
