tion.
3. Start at collar on burner enclosure (inside boiler
jacket) and work towards the correct air intake
terminal for installation.
4. Install two (2) foot section of single wall metal pipe
(provided) onto burner enclosure collar.
Note: RV3-RV4 uses 3 inch diameter pipe
RV5-RV7 uses 4 inch diameter pipe
* The PVC air intake kit (P/N 6116054), if used, will
increase air intake pipe diameter to 4 inch.
a. Secure with three (3) sheetmetal screws.
5. If installing an RV3 or RV4 the use of a 4 inch x 3
inch reducer is required (provided). If installing an
RV5 through RV7, proceed to Step 7.
a. Secure 4 inch x 3 inch reducer onto two (2) foot

a. Secure with three (3) self-drilling sheetmetal
screws provided.
7. Maintain minimum of ¼ inch per foot slope on
horizontal runs. Slope down towards boiler.
8. The air intake pipe must be adequately supported
with straps or supports no less than five (5) feet
apart on horizontal runs. The complete air intake
piping system must be rigid and able to withstand
minor impacts without collapse.
9. Connect air intake piping to appropriate air intake
terminal for desired installation.
a. Join PVC air intake piping to terminal using
PVC coupling provided. See Figures 21 and 22.
Note: RV3-RV4 separate horizontal/vertical
installations will require the 4 inch x 3 inch
decreaser (provided) in addition with the PVC
coupling to join the air intake piping and air
intake terminal. See Figures 21 and 22.
b. Secure PVC to terminal or decreaser with three
(3) self-drilling sheetmetal screws provided.
