Controls
The F60 thermostatic on/off remote with digital screen is included with the BX42 fireplace. The F60 choice in this group is for a separately purchased replacement only; no extra remote purchase is needed for the standard fireplace package. W660-0081 is an optional wall-mount digital thermostat. Napoleon also lists EFCN-PF0 for natural gas and EFCP-PF0 for propane as optional eFIRE Bluetooth controllers for PF0 controls; choose the controller matching the fireplace fuel.
Venting
A complete approved 5-inch inner / 8-inch outer direct-vent system is required for installation and sold separately. The venting selector is optional for ordering and is listed after other accessories. Choose components for your installer-approved route: horizontal kits, individual wall or roof terminations, flex lengths, and installation accessories are alternatives or route-dependent parts, not items to purchase all together. Roof terminals need the appropriate vent lengths; a single terminal or accessory is not a complete system. Do not mix vent sizes. For the BX42 power-vent configuration, pair the GPV terminal with the PVA-58ASCENT adapter kit. The BX42 manual specifies top-vent use for power venting. The adapter includes a 5/8-inch to 4/7-inch reducer; do not assume the standard 5/8-inch natural-draft components above form a complete power-vent system. Follow the GPV, adapter and appliance instructions for vent routing and electrical connections. The terminal and adapter are separate items and both are needed for this power-vent configuration.
