Metro Vancouver install considerations
NFB-specific install notes:
- Heavier unit (90-180 lbs): Wall mounting requires reinforced studs or wall anchors rated for the weight
- Gas line typically 1": Most residential needs upgraded from 3/4" if the existing line is short
- Venting up to 4": Larger BTU models require larger venting; we route appropriately
- Outdoor reset essential for condensing efficiency at high BTU loads
- Cascade installs: Multi-unit cascade communication wiring during install

Frequently asked questions
Whats the difference between NFB and NCB-E?
NCB-E has a water-tube heat exchanger; NFB has a fire-tube. Fire-tube handles scaling better, modulates wider (15:1 vs 10:1), and is the premium tier. Real-world lifespan 18-22 years vs 12-18 for NCB-E.
Is the NFB worth the price premium?
For homeowners planning to stay 15+ years, yes — the longer lifespan typically delivers lower total cost-of-ownership. For shorter ownership, the NCB-E is the better-value pick.
Can the NFB cascade for a large home or commercial?
Yes — up to 16 units in cascade. Manages massive BTU loads from a single control system. CANRO does residential cascade installs and light commercial.
What size NFB do I need?
For most premium-tier residential: 199K BTU single unit handles up to 4,500 sq ft. Larger requires cascade. CANRO runs heat-loss for every quote.
FortisBC rebate?
Yes — up to $1,500 same as other Navien condensing units.
How long does install take?
Single unit: 1 day typically. Cascade installs: 2-4 days depending on complexity.
Is service support different for NFB?
Same Navien parts network — excellent BC availability. CANRO carries common NFB parts.
Free consultation?
Yes — every CANRO NFB quote starts with a free in-home consultation including heat-loss calc.
Whats the smallest NFB?
110K BTU. The fire-tube design has higher cost per BTU than the NCB-E water-tube, so for smaller homes the NCB-E usually makes more sense.
Can it pair with a heat pump for hybrid heating?
Yes — the NFB can act as the gas backup in a hybrid heat-pump system. Common in BC homes wanting to capture heat-pump rebates while keeping gas backup for the coldest days.
