Choosing the right model

Three things to check before you order.

1. Fuel type

Match the gas supplied to your home. Model numbers ending in N run on natural gas, P on liquid propane.

2. Indoor or outdoor

Indoor units (i) vent through a wall or roof. Outdoor units (e) mount on an exterior wall with no venting.

3. Size (BTU & GPM)

More fixtures running at once need a higher flow rate. 160K–199K BTU units suit most 2–4 bathroom homes.
