Hayward H Series 135,000 BTU Electronic Natural Gas Swimming Pool Heater
## Hayward H-Series 135,000 BTU Electronic Natural Gas Pool Heater (Low Altitude)
Extend your swimming season with the superior thermal efficiency of the all-new Hayward H-Series 135,000 BTU Natural Gas Heater. Engineered to deliver exceptional heating velocity and unmatched value for permanent above-ground pools and heavy-duty spas, this model features an advanced **fan-assisted combustion system** that ensures continuous, reliable heating performance even during high-wind or colder shoulder seasons.
Standing out as the **only above-ground pool heater in its class to feature a professional-grade Cupro-Nickel heat exchanger as standard**, the W3H135FDN offers premium corrosion resistance. This heavy-duty alloy provides an exceptional defensive shield against harsh chemical fluctuations and high-velocity water erosion, making it fully compatible with **saltwater pool environments** where standard copper heaters rapidly degrade.
### Reliable Thermal Delivery & High-End Metallurgy
* **Standard Cupro-Nickel Heat Exchanger:** Premium copper-nickel alloy provides enhanced protection against corrosive water chemistry, chemical spikes, and salt-chlorine environments for a significantly longer product life.
* **Fan-Assisted Forced Draft Technology:** Employs a specialized combustion fan that forces a constant fuel-to-air mix, guaranteeing dependable BTU delivery regardless of ambient wind or erratic outdoor conditions.
* **Digital Electronic Thermostat:** Outfitted with an intuitive digital control board for precise temperature adjustment, immediate diagnostic feedback, and maximized thermal fuel efficiency.
* **Plug-and-Play Control Power:** Comes equipped with a convenient **110V power plug** to effortlessly supply the digital control interface and internal fan system.

### ⚠️ Strict Operational Boundaries & Application Restrictions
* **Altitude Warning:** This unit is calibrated exclusively as a **low-altitude heater**; it will **NOT** operate safely or correctly at elevations above 2,000 feet due to atmospheric air-to-fuel gas mix limits.
* **Absolute Soft-Sided Pool Ban:** This thermal system is **strictly incompatible with soft-sided or temporary pools** (such as Intex, Coleman, or Bestway) due to their insufficient plumbing flow rates. Installing this gas heater on any soft-sided pool setup **instantly voids all factory warranties** and creates immediate operational risks.
---
### ⚠️ Installation & Factory Warranty Guidelines
* **Factory Warranty Policy:** Backed by a 1-Year Manufacturer’s Limited Warranty from the purchase date, covering factory replacement parts and labor at the manufacturer's discretion.
* **Licensed Trade Requirement:** To validate and preserve active warranty protections, this natural gas equipment must be anchored, wired, and connected exclusively by a **certified pool technician, licensed gas fitter, or professional electrician**. Proof of a licensed professional installation is **strictly mandatory** to process any future parts or labor claims.
* **Water Chemistry Exclusions:** Scaling, corrosion pitting, or heat exchanger failure resulting from poor water balance (out-of-bounds pH, low total alkalinity, or improper chemical dosing) is explicitly excluded from warranty coverage.
