The size of the return air grill depends on the size of the forced air fan. The return air grid to reduce noise should be 5 to 8 times the size of the fan outlet. A 36000 btu heating system often has between a 500 to 1500 CFM fan the outlets on these fans are often between 30 and 80 square inches so the grid should be between 150 and 600 square inches (depending on the fan), the bigger you can fit the better. If you can fit it I'd put in a 12 x36 grill (432 sq in) but a 12 x 24" (288 sq inch)grill should work well too.
